Above each punnet square, the genotypes of the parents were given right? something like this:
Parent 1 fur genotype: Ff Parent 1 eye genotype: Ee
Parent 2 fur genotype: Ff Parent 2 eye genotype: ee
F f E e
F FF Ff e Ee ee
f Ff ff e Ee ee
Probability of black fur if dominant is: Probability of red eyes:
3/4 2/4= 1/2
Probability of a trait combination such as black fur and red eyes is
3/4*1/2 = 3/8.

In humans, B is the allele for brown eyes and b is the allele for blue eyes. Two brothers both have brown eyes, but one of them has both the B and b alleles while the other only has B alleles. Which statement is true about the brothers?
Answer:
B is the dominate trait, and b is the recessive trait. Putting them together (Bb), would still mean that the brother would have brown eyes, since Bb means that the dominant trait is shown
bb- recessive trait (blue eyes)
Bb - dominant trait (brown eyes)
BB- dominant trait (brown eyes)

Kyree is heterozygous. |f(W) ) is for waves, and ) if for no wave (w) r no waves What is Kyree's genotype & phenotype?
Answer:
Kyree b will have waves with a gwnotyoe; We
Explanation:
This question involves a single gene coding the possession or not of waves in humans. Allele W is for possession of waves while allele w is for no waves.
Heterozygous means contains two different alleles of the same gene. In this case, an heterozygous individual will possess allele W and w together i.e. Ww. Since the allele W is dominant over allele w i.e. can mask Its phenotypic expression, an heterozygous offspring (Ww) will phenotypically possess waves.
Whats the carrying capacity?
Answer:
2003-25
Explanation:
To find carrying capacity on a graph, you need to locate the point on the graph where the population line is horizontal. Alternatively, the carrying capacity may be explicitly marked with a dotted horizontal line or a horizontal line of a different color.
Jacque is hiking in the mountains and sees a very large and colorful rock layer. It looks different than the surrounding rock layers. What is the best way for Jacque to investigate what the environment was like when this rock layer was deposited?
Jacque could measure the height of the rock layer.
Jacque could check if the rock layer has fossils in it.
Jacque could look at the color of the surrounding rock layers.
Jacque could chip off a chunk of rock from the rock layer and smell it.
Answer:
Check if the rock layer has fossils in it.
Explanation:
The rock layer from the inside out and the fossils will tell you how old the rock is.
Jacque could check if the rock layer has fossils in it, as the presence and types of fossils can often provide clues about the environment in which they were formed.
What can a rock layer tell about the environment?To investigate what the environment was like when a rock layer was deposited, there are several approaches that can be taken:
Look for clues in the rock layer itself: The rock layer itself can often provide clues about the environment in which it was formed. For example, the presence of certain minerals or fossil types can indicate the presence of specific conditions, such as warm or cold temperatures, or a marine or terrestrial environment.
Examine the surrounding rock layers: The rock layers above and below the rock layer of interest can provide additional context and clues about the environment. For example, if the surrounding layers are sedimentary rocks, such as sandstone or shale, it may indicate that the area was once covered by water.
Use rock dating techniques: As mentioned earlier, techniques like radiometric dating and relative dating can help determine the age of a rock layer and provide insight into the environment that existed at the time it was formed.
Conduct additional analyses: Depending on the type of rock and the questions being asked, it may be possible to conduct more detailed analyses, such as chemical or isotopic analyses, to gather further information about the conditions under which the rock formed.
Consider the current location of the rock layer: The current location of the rock layer can also provide clues about the environment in which it was formed. For example, if the rock layer is found in a mountain range, it may have formed in a tectonically active area, while a rock layer found in a flat, low-lying area may have formed in a more stable environment.

What is a Schwarzchild radius and what does it have to do with a black hole
Answer:
The Schwarzschild radius (sometimes historically referred to as the gravitational radius) is a physical parameter that shows up in the Schwarzschild solution to Einstein's field equations, corresponding to the radius defining the event horizon of a Schwarzschild black hole
Explanation:
The Schwarzschild radius define the “size” of a black hole. Theorists believe that all the “stuff” inside a black hole collapses into a singularity, an infinitely small and infinitely dense point well inside the boundary defined by the Schwarzschild radius.

What percent of the offspring will be red, if we cross two pink tulips?
75 %
50 %
25 %
Answer: 50
Explanation:you are combining two pink to the possibility of the tulips being red will be 50 50
It is a case of incomplete dominance. 25% of the offspring will be red. Therefore, option C is correct.
What is incomplete dominance?When two heterozygous alleles in a gene interact with each other, their traits are expressed partially, because they both are not dominant on each other. This type of dominance is called incomplete dominance.
It is not necessary to do a test to identify the heterozygous in incomplete dominance. The phenotype and genotype ratio is the same in this dominance. Incomplete dominance is different from co-dominance.
When two heterozygous pink tulips (Rr) cross, then 25% red (RR), 50% pink (Rr), and 25% white (rr) tulip flowers are produced. The phenotype and genotype ratio will be 1:2:1. Therefore, option C is correct.

Mendel made crosses between pure-breeding tall pea plants with purple
flowers and pure-breeding short pea plants with white flowers. The alleles for
a tall height and purple flowers were dominant. This cross is written as
A. TtPpx TtPp
в. TTppx ttPP
с. Ttppx TtPP
D. TTPPx ttpp
Answer:
D
Explanation:
He bred two true-breeding strains initially. That means the alleles were homozygous for each gene.
Let's use Tt to represent the height allele: T means tall, t means short; the dominant allele gets the capital letter.
Let's use Pp to represent the flower color allele: P means purple, p means white.
A pure-breeding tall, purple plant would be TTPP.
A pure-breeding short, white plant would be ttpp.
So the cross is D. TTPP x ttpp.
Answer:
The correct answer is - ttPP × TTpp

Independent assortment is the exchange of genetic material between
homologous chromosomes.
True Or False
Answer:
False
Explanation:
According to Gregor Mendel in his law of INDEPENDENT ASSORTMENT, independent assortment of genes is a phenomenon whereby the segregation of the alleles of one gene into gametes occurs independently of the alleles of another gene i.e. their segregation does not affect/influence one another. Independent assortment occurs in the Metaphase 1 of meiosis 1, where homologous chromosomes randomly align at the equator of the cell. This random orientation of homologous chromosomes determines which chromosome will separate into which gamete.
According to the question, the exchange of genetic material between homologous chromosomes is termed CROSSING-OVER. Crossing over or Recombination occurs during the Prophase I state of meiosis I, where non-sister chromatids of homologous chromosomes exchange a portion of their gene.
Hence, the answer is false because the exchange of genetic material between homologous chromosomes is crossing-over.
