In Unicorns diamond eyes are dominant over emerald eyes. Two unicorns with diamond eyes have 4 babies. 1 of their babies has emerald eyes.

A. What is the genotype of the two parent unicorns?

B. What are their chances of having another baby with emerald eyes?
Help pleaseee!!

Answers

Answer:

A. Their genotype is Ee.

B. They have a 25% or 1 out of 4 chance of having an offspring with emerald eyes.

Explanation:

A. If one of the babies has emerald eyes, it means it has 2 recessive alleles. so, its genotype is ee. If the parents have diamond eyes, they have to have at least one dominant allele, but they cannot have 2 dominant alleles because one of their offspring have diamond eyes. So, their genotype is Ee.

B. The parents have a 25% or 1 out of 4 chance of having an offspring with emerald eyes, and 75% or 3 out of 4 chance of having offspring with diamond eyes.    

Two unicorns with diamond eyes have 4 babies. 1 of their babies has emerald eyes. A.  the genotype of the two parent unicorns  Ee.

B. Their chances of having another baby with emerald eyes will have 25% or 1 out of 4 chance of having an offspring with emerald eyes.

What is genotype ?

A genotype is the set of heritable genes transferred from parents to offspring in next generation; These genes are essential as it involve in encoding specific functional protein needed for body

The genetic characteristics can be physically expressed in an organism called as phenotype.

The genotypes can be written in three form on the basis of allele arrangement such as homozygous dominant (PP), Heterozygous (Pp) and Homozygous recessive (pp).

In case 1 if one of the babies has emerald eyes, that is 2 recessive alleles, then the genotype is ee. If the parents have diamond eyes, with at least one dominant allele, then the genotype is Ee.

Why do cells hold chromosomes?

Answers

There the DNA is organized in individual chromosomes in the form of very long filaments.Therefore, to ensure safe transport of DNA during cell division the long and coiled DNA fibers must be tightly packed.
Chromosomes are the genetic information that is contained by the nucleus (in some cells) and without chromosomes cell division would not occur

Why do we need human dna

Answers

DNA. Deoxyribonucleic acid (DNA) is a nucleic acid that contains the genetic instructions for the development and function of living things.

All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information.

We need human DNA since it give us the long term info storage, which is needed

DNA contains instructions for development, survival, and reproduction. DNA sequences must be translated into signals to make proteins, which do most of our body's job.

What is human genome?

DNA stores the instructions that are necessary for an organism to grow, maintain its existence, and reproduce itself. In order for these duties to be carried out, the sequences of DNA need to be transformed into messages that can be utilized in the production of proteins. Proteins are the complex molecules that are responsible for the majority of the work that is done in our bodies.

The human genome is comprised of all of the nucleic acid sequences that are found in humans. These sequences are stored as DNA within the 23 chromosome pairs that are found in the nucleus of cells, as well as in a tiny DNA molecule that is located within the mitochondria of each individual cell. In most cases, these are considered to be two distinct components: the nuclear genome and the mitochondrial genome.

Explanation:

Some bears, become very effective predators on newborn elk, moose, deer or caribou. Others live in areas where salmon, su.ckers or other fish spawn for part of each year.

When bears emerge from their dens in the spring, food is in short supply. Although bears are hungry, most trees and shrubs won’t leaf for another month and only the grass at lower elevations has begun to green up.

In Alaskan malamute dogs, the allele for dwarfism (d) is recessive to the allele for normal-size dogs (D) and the allele for white coat colour (r) is recessive to the allele for brown coat colour (R). A breeder crosses two malamute dogs, both of normal-size and brown coat colour multiple times. During these multiple times, the following puppies were produced: Normal-size/brown coat colour: 18 Normal-size/ white coat colour: 6 dwarfism/brown coat colour : 6 dwarfism/white coat colour: 2 What genotype are the parent dogs?

Answers

Answer:

DdRr

Explanation:

The parents are heterozygous with the genotype DdRr.

Assuming the two genes are independently assorting. For standard, independently assorting genes, the phenotypic ratio for a dihybrid cross should be 9:3::3:1 with the domiant parental gene having the highest frequency, the recessive parental genes having the lowest frequency and the recombined genes having the intermediate frequencies.

DdRr   x   DdRr

Progeny

9 D_R_  normal size, brown coat

3 ddR_   dwarf, brown coat

3 D_rr     normal size, white coat

1 ddrr      dwarf, white coat.

The phenotypic frequency is 9:3:3:1.

Now let us look at  phenotypic frequency of the outcome

18:6:6:2 is also equivalent to 9:3:3:1.

Hence, the parents are hetezygous with the genotype DdRr.

Use what you know about natural selection to fill in the blanks in the hypothesis. It should answer the lab question, “What is the effect of the type of food available on the frequency of different types of bird beaks?”

Hypothesis: If the type of food available changes, then…


Answers

Answer:

For example, if the seeds that the bird needs to eat is bigger, over time it will adapt to get a bigger beak to eat the bigger seed. The birds that have adapted reproduce and soon more and more birds that have a bigger beak for the bigger seed are more common. If the type of food available changes than the bird will most likely adapt to eat that food.

- What do the resistant fleas do that the sensitive fleas do not?

Answers

Answer:

Explanation:

The dog has fleas, but the medicine to counter this does not work. This means that the fleas have built up a resistance against the drug to ensure continued survival and reproductive success of these organisms. These resistant fleas may have existed in population as the population is always large but in small amounts. Thus, treatment with the drug will lead to the dieing out of the sensitive fleas and then leaving the resistant fleas with the favourable alleles to be selected for.

These favourable traits that have evolved against the drugs are then selected for and the organisms reproduce giving rise to more fleas with these favourable characteristics (being resistant to the drugs) such that their continued survival and reproductive is ensured compared to the sensitive fleas that die out.
