Q: Two genes in tomatoes are 61 mu apart; normal fruit (
Two genes in tomatoes are 61 mu apart; normal fruit (F) is dominant to fasciated (flattened) fruit ( f ), and normal number of leaves (Lf ) is dominant to leafy (lf ). A true-breeding plant with norma...
See AnswerQ: In the tomato, three genes are linked on the same chromosome
In the tomato, three genes are linked on the same chromosome. Tall is dominant to dwarf, skin that is smooth is dominant to skin that is peachy, and fruit with a normal rounded tomato shape is dominan...
See AnswerQ: A trait in garden peas involves the curling of leaves. A
A trait in garden peas involves the curling of leaves. A two-factor cross was made by crossing a plant with yellow pods and curling leaves to a wild-type plant with green pods and normal leaves. All F...
See AnswerQ: In mice, the gene that encodes the enzyme inosine triphosphatase is
In mice, the gene that encodes the enzyme inosine triphosphatase is 12 mu from the gene that encodes the enzyme ornithine decarboxylase. Suppose you have identified a strain of mice homozygous for a d...
See AnswerQ: In the garden pea, several different genes affect pod characteristics.
In the garden pea, several different genes affect pod characteristics. A gene affecting pod color (green is dominant to yellow) is approximately 7 mu away from a gene affecting pod width (wide is domi...
See AnswerQ: A sex-influenced trait is dominant in males and causes bushy
A sex-influenced trait is dominant in males and causes bushy tails. The same trait is recessive in females. Fur color is not sex influenced. Yellow fur is dominant to white fur. A true-breeding female...
See AnswerQ: Three recessive traits in garden pea plants are as follows: yellow
Three recessive traits in garden pea plants are as follows: yellow pods are recessive to green pods, bluish green seedlings are recessive to green seedlings, creeper (a plant that cannot stand up) is...
See AnswerQ: In the experiment of Figure 6.6, Stern followed the
In the experiment of Figure 6.6, Stern followed the inheritance pattern in which females carried two abnormal X chromosomes to correlate genetic recombination with the physical exchange of chromosome...
See AnswerQ: Explain the rationale behind a testcross. Is it necessary for one
Explain the rationale behind a testcross. Is it necessary for one of the parents to be homozygous recessive for the genes of interest? In the heterozygous parent of a testcross, must all of the domina...
