Question

A single gene mutation in cats can result in curly ears( see image) . The cats are healthy and normal beyond there ear structure. This trait is recessive, in the allele for curly years is $in the ally for a regular ears is S. Which of the following responses are true?

Please help

Answer 1

The true statements are:

A cross between this cat and another curly ear cat will result in 100% curly ears.

The genotype of the cat in the picture is CC.

Let's analyze each statement:

Cats are found on all planets in our solar system.

This statement is not related to the genetic trait described and is not addressed by the information provided. It's not possible to determine its truth based on the information given.

A cross between this cat and another curly ear cat will result in 100% curly ears.

If the cat in the picture has a genotype of CC (where C represents the allele for curly ears), and if the other curly ear cat also has the genotype CC, then their offspring would indeed have 100% curly ears. So, this statement could be true, assuming the genotype of the cat in the picture is CC.

The genotype of the cat in the picture is $$

The genotype described here is not consistent with the information provided. The alleles are represented by C and S, not $$. The correct representation would be CC for curly ears.

Mutations are always bad, even in cats.

This statement is a generalization and not necessarily true. Mutations can be neutral, harmful, or beneficial depending on the context. In this case, the mutation leading to curly ears seems to be a benign trait, as the cats are described as healthy and normal beyond their ear structure.

The genotype of the cat in the picture is S$

Similar to statement 3, the representation S$ is not consistent with the information provided. The correct representation for the genotype associated with curly ears is CC.

A cross between this cat and another curly ear cat will result in 100% straight ears.

This statement is not true. If both cats have curly ears (genotype CC), their offspring would inherit at least one curly allele, resulting in curly ears.

The phenotype of the cat is $$

The phenotype is the observable trait, and in this case, it's described as curly ears. The correct representation would be curly ears, not $$.

A cross between this cat and another curly ear cat will result in 75% straight ears.

This statement is not accurate. If both parents have curly ears (genotype CC), the expected outcome of a cross would be 100% curly ears in the offspring.

So, the true statements are:

A cross between this cat and another curly ear cat will result in 100% curly ears.

The genotype of the cat in the picture is CC.

Answer 2

The correct statement about the cat in the picture is B which the cross of this cat with a curly cat will produce 100% curly ear cats.

Step-by-step explanation:

According to the given statement of the question,the curly ear is a recessive trait and allele for this trait is $.

So the genotype will be homozygous recessive which is $$.

Hence by crossing a $$ cat with another curly ear cat $$ will produce offspring which are identical in genotype $$ and all will have curly ears.

Hence the statement, "the cross of this cat with a curly cat will produce 100% curly ear cats" is a correct statement.
