Coat color in cats is a codominant trait and is also located on the X chromosome. Cats can be black, orange or calico. A calico cat has black and orange splotches. In order to be calico. the cat must have an allele for the black color and an allele for the orange color. Use a punnett square to show why there are no male calico cats.

The study of genes and inheritance is called genetics.

The correct answer to the question is due to the presence of the Y chromosome.

According to the question, the color coat of the cat is a codominant trait and is present on the X chromosome.

The X chromosome is present on the female and the male has the Y chromosome. The father only inherits the Y chromosome to his son.  The color coat gene is present on the X chromosome due to which it can not be transmitted from father to his son.

Parents       GENES          Gametes

Male            XY               X     Y

Female         XX              X      X

The offspring ratio will be XX: XY that is 1: 1

Hence, the correct answer is mentioned above.

The males can only either be black or orange

Explanation:

There can be no male calico because for an offspring to be a calico the two codominant alleles must each be carried on the two X chromosomes and in the males, there is the presence of just one X chromosomes, thus they can either be black or be orange. For the females, the can only be black if they carry the black allele on both X chromosomes, the same goes for the orange.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
