The brown-haired partner has one parent who has red hair. Write down letter designations for the alleles. Pure-breeding tall and short plants are crossed.
What will be the genotype and phenotype of the F1? What is the genotype of the brown-haired parent with respect to hair color?
Dominant and Recessive 4. The second child is albino. If the F1 is self-bred and F2 plants are raised, how many would be expected in each phenotypic class?
A recessively inherited form of albinism causes affected individuals to lack pigment in their skin. What would be the genotype of a male solid black rabbit whose parents were homozygous for the black allele? Practice with genetic problems is essential for mastering the basic principles of heredity—no amount of reading and memorization can substitute for the experience you will gain by solving problems in genetics.
Rabbits can have solid or spotted coats, and the base color can be either brown or black.
Complete the following problem by answering the following questions. In the pea, tall plant height T is dominant over short t. What kinds of gametes would be produced by the solid black rabbit? Be sure to distinguish between the two traits, and be sure to consider which alleles are dominant and recessive.
For example, Mendel used P to designate the purple allele, and p to designate the white allele for pea flower color. Haploid and Diploid 6.
Albinism and hair color are governed by different genes. In hair color, red hair is inherited as a recessive trait, and brown hair is inherited as a dominant trait.
The first child is normally pigmented and has brown hair. What is the genotype of the albino parent for hair color? An albino woman whose parents both have red hair has two children with a man who is normally pigmented and has brown hair.
Gametes and Zygotes Not only are the principles of segregation and independent assortment important because they explain how heredity works, but they also provide the means for predicting the outcome of genetic crosses.
Genotype and Phenotype 3. Spotted coat color is dominant to solid, and black is dominant to brown. How many of the F2 would be expected to be pure-breeding when self-bred? If you cross these two rabbits, what kinds of gametes would be produced by the spotted brown rabbit?
This predictive power has made genetics a powerful tool in agriculture and other fields, and the ability to apply the principles of heredity is an important skill for you as a student of genetics. Locus and Allele 2. What is the genotype of the first child with respect to hair color and skin pigmentation?

Directions: Using the data in Table 1, write the genotype that corresponds to the phenotype descriptions. The video explains this type of genetics with many guided practice problems. It covers incomplete dominance, codominance, and sex-linked traits.
