Answer:

Explanation:

Hi there!

We are given the hair types of two cats

The first one has long hair, and it's heterozygous, meaning it has one dominant, and one recessive allele. We are given that it is a carrier of the short hair allele, meaning in its genotype, it has the short hair gene (that doesn't necessarily mean it's there in its phenotype). However, since it has long hair (genotype), that means that the long hair allele is dominant (the gene that will always show), and the short haired one is recessive (the gene that gets "covered up" by the dominant allele). Let's say the genotype of the long haired cat is Tt, where T is the long hair, and t is the short hair  

The second cat has short hair, and as we have mentioned above, the allele for short hair is recessive, so the short haired cat has 2 copies of the short hair allele. Its genotype is tt

Please see below for the Punnett Square

Hope this helps! :)

In pigs, curly tails (T) are dominant over straight tails (t). If a pig is heterozygous for a curly tail, what is the pig's geno
n200080 [17]

Answer:

The pig's genotype is Tt

Explanation:

As mentioned in the question that curly hair allele T is dominant over straight tail allele t.

A heterozygous organism is that in which both alleles for a trait are different. Since Curly hair allele T is dominant over straight tail t, it means that the pig with curly tail and heterozygous genotype will definitely have a genotype of Tt.

Hope it helps! :)

Explain the relationship between crossing over and genetic variation
diamong [38]

Answer:

Crossing over is termed as a process by which genetic materials are exchanged by non-sister chromatids during meiosis. Crossing over results in the new combination of information in genetic for, the cell for a specific trait. It ensures that organisms are identical from one generation to another.

Edith and her pal Dave love to catch butterflies in the nearby fields! The fields are home to a special type of green butterfly
wlad13 [49]

Answer:

The probability of obtaining a "goober" butterfly is 6.25%

Explanation

If there are three possible combinations of butterflies, with yellow and blue being dominant, green is supposed to contain a recessive pattern, so according to Mendel's law of character independence, the pattern RR and BB manifest the dominant phenotype yellow, blue or yellow and blue in spots, the green pattern must be recessive is represented by the letter a, the punnett graph is made, obtaining that 56% present a dominant pattern, 37.5% will be spotted and the pattern recessive must match to generate 6.25% of butterflies “goober”.
