Let the heterozygous be represented by Tt;
and the homozygous recessive be tt.
Thus, Parents Tt tt
Gametes T t t t
Offsprings Tt Tt tt tt
Thus, out of 4 offsprings, 2 are tt i.e homozygous recessive.
Thus, correct answer is 50%

35. A testcross (backcross) is used to determine: a. an individual has a dominant or recessive phenotype. b flowers are red, pink, or white c. whether an individual is homozygous or heterozygous. d. what types of offspring could be produced 36. If red flower color is dominant over white and a homozygous red flowered plant was crossed with a homozygous white flowered plant, what percentage of their offspring in the Fi generation would have white flowers? a. b. с. 100%...
Question 31 (1 point) In pea plants, round (R) seeds are dominant to wrinkled (r) seeds. In a genetic cross of two pea plants where one plant is heterozygous for the seed shape trait and the other is homozygous for the recessive (r) trait, what percentage of the offspring would have the wrinkled seed shape? O a) 25% Ob) 100% O c) 50% O d) 75% Question 32 (1 point) In pea plants, green (G) seeds are dominant to yellow...
In simple Mendelian inheritance alleles display a simple dominant/recessive relationship. There are many exceptions to Mendelian laws of inheritance. Most genes have more than two allelic forms and do not exhibit simple Mendelian inheritance. The human ABO antigens are an example of a multiple allelic trait. There are three ABO blood group antigens, IA, IB and i. The i allele is recessive to both IA and IB. A person who is homozygous ii has type O blood and does not...
