Among Dogs, Short Hair Is Dominant to Long Hair and Dark

question 3

Essay

Among dogs, short hair is dominant to long hair and dark coat color is dominant to white (albino) coat color. Assume that these two coat traits are caused by
independently segregating gene pairs. For each of the crosses given below, write the most probable genotype (or genotypes if more than one answer is possible) for the
parents. It is important that you select a realistic symbol set and define each symbol below.
Assume that for cross (d), you were interested in determining whether fur color
follows a 3:1 ratio. Set up (but do not complete the calculations) a Chi -square test for these data [fur color in cross (d)].

Definitions:

Meiosis

A process of cell division in sexually reproducing organisms that reduces the number of chromosomes in reproductive cells to half, leading to the production of gametes or spores.

Parental Chromosome Number

The parental chromosome number refers to the specific number of chromosomes found in the genetic material an organism inherits from its parents, typically half from each.

Parent Cell

The cell that divides to give rise to daughter cells during cell division.

Chromosomes

Thread-like structures located inside the nucleus of animal and plant cells, made of protein and a single molecule of DNA.
