Question

2. In certain cats, tail length-long, short, manx (no tail) - is determined by a gene that demonstrates incomplete dominance. a. Make up letters to represent the long & manx alleles. b. Give the genotypes for each tail type. Long-tailed Short-tailed Manx c. Construct a Punnett square to illustrate a cross between a short-tailed cat and a man. What is the probability that the resulting kittens will be manx? Activity 3: Codominance 1. In codominance, the symbols for alleles are expressed as superscripts. For example, fur color in certain cats is determined by the F gene. The Fallele codes for black fur, while the Frallele codes for tan fur. Cats that inherit both alleles exhibit the tabby pattem (black & tan striped fur). Note that the alleles are equally dominant - mixtures of both black and tan hairs appear in the heterozygote. a. List the genotypes of each type of cat. Black Tabby Tan b. What are the genotypes of the gametes that each of the following individuals can produce? Black Tabby Tan 99

Answer 1

Ans) in incomplete dominance both the traits will be expressed for eg if male flower is red and female flower is white the offspring would be pink in case of incomplete dominance as the two genes will merge.

In co dominance with the same example, when male plant is red and female is white the offspring would be half white and half red. The offspring would show both the colour trait and would not merge.

black - White - B would represent black b for white. Black - BB checkered -Bb white - bb BB X BB - BB BB BB BB. Black & white BB X bb. b b BL Bb Bb B Bb | Bb. ③ white & white bb bb in bb bb.

if this helps gob e it a positive rating thank you.
