Mendel conducted many different dihybrid crosses of pea plants. He found very similar phenotypic ratios in each second generation, regardless of the combinations of traits.   Based on these results, what did Mendel state in his law of independent as

Tay-Sachs disease is inherited in an autosomal recessive manner. Which term is used to describe a person who has the gene for Tay-Sachs, but does not have the disease?

Which sentence BEST expresses a main idea stated in Mendel's law of segregation?

A heterozygous plant (Ss) is crossed with a plant homozygous dominant (SS) for smooth petals. S is dominant for smooth petals, and s is recessive for wrinkled petals. What will MOST LIKELY be the petal texture of the first generation of offspring?

A fruit fly is heterozygous for both eye color and wing length (EeWw).    E is dominant for yellow eyes. e is recessive for white eyes. W is dominant for long wings. w is recessive for short wings. What would be the distribution of gametes?

The genotype of a female pea plant is SSTt. Which combinations of alleles could be present in gametes produced by this plant?

In order to produce gametes with the genotypes BF, Bf, bF, and bf, what MUST the genotype of the parent be?

Mrs. Bage started a pea farm, but only planted green peas. When these plants were crossed, they noticed that the plants produced green, yellow, and white peas during the first growing season. What is MOST LIKELY the reason for the difference?

Researchers crossed a heterozygous tall pea plant (Tt) with a homozygous short pea plant (tt). What is the probability that this cross will produce homozygous short (tt) offspring?

Having a widow's peak is the dominant trait (W), while lacking a widow's peak is the recessive trait (w). If 100% of the offspring are heterozygous, what are the genotypes of the parents?
