2) In pea plants, round seed shape (R) is dominant over wrinkled (r). Write the genotype and phenotype for a plant that is: A) Heterozygous (hybrid), B) Homozygous dominant (pure), and C) Homozygous recessive (pure).

Answer:A) Rr

B) RR

C) rr

Explanation:

A) Heterozygous hybrid

Genotype phenotype Rr Round seed.

B) Homozygous dominant pure. Genotype phenotype RR Round seed

C) Homozygous recessive

Genotype phenotype rr wrinkled seed

Dominant gene is a gene that expresses itself in the phenotype of an individual

Recessive allele is an Allele whose effect is masked by a dominant allele but can only express itself in homozgous form.

Homozygous is two allele that are the same e. g AA

Heterozygous is 2 Allele that are different e. g Aa
