Answer 1

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
