Parents often want to know what is genetically possible for their children. If two parents arecarriers for a recessive lethal trait, what are the odds that their child is also a carrier?Many times there is interest in tracking multiple traits at once (not just 1 or 2). The sameprobability rules apply here, you just multiple all the odds together at once. Imagine twoparents. They are both carriers for red hair, one person is blood type AB, the other is type O.They want to know the odds of a daughter with red hair and type B blood. Please do no not doa giant Punnett square! Use probability or individual squares.a. What are the genotypes of the parents?b. What are the odds of each trait (daughter, red hair, type B)

To answer problem number 2: The parents are both carriers for red hair (Rr), and we need to…

Armin and Annie are going to have a baby. Annie has dimples in her cheeks (a dominant trait), while Armin does not. You know that Annie's father has dimples in both cheeks, while her mother does not. Her mother must have the recessive trait. Annie's father has the dominant trait, but you don’t know if he is a homozygote or heterozygote. But you still know what Annie’s genotype must be because Annie must have a recessive allele since that is all she could have inherited from her mother. Since Annie has a dimples you know she inherited a dominant allele from her father. What are the chances Armin and Annie’s baby will have dimples? Determine the Phenotype and Genotype and its probability.
A genetic engineer is going to cross two watermelon plants to produce seeds for a spring planting. He is breeding for size, and wants to have as many watermelons with the phenotype for long shape as possible. In watermelons, the allele for short shape (R) is dominant to the allele for long shape (r). Would crossing a watermelon homozygous recessive for the trait with a watermelon heterozygous for the trait give the most long watermelons possible? Explain your answer using Punnett Squares.
Brown eyes are dominant over blue eyes. This is NOT a sex linked trait. Cross a brown eyed Color blind male (whose mother had blue eyes) with a normal blue eyed female (whose father was colorblind)
Albinism is an autosomal (not sex-linked) recessive trait. A man and woman are both of normal pigmentation and have one child out of three who is albino (without melanin pigmentation). What are the genotypes of the albino's parents? One parent must be homozygous for the recessive allele; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be homozygous dominant. One parent must be heterozygous; the other parent can be homozygous dominant, homozygous recessive, or heterozygous. Both parents must be heterozygous. One parent must be homozygous dominant; the other parent must be heterozygous. O000
