Answer 1

Answer:

Dominant allele = R

Heterozygous Red = Rr

Homozygous red = RR

Homozygous white = rr

Monohybrid cross = Rr × Rr

Recessive allele = r

Explanation:

In this Punnett square, dominant alleles with capital letters are regarded as dominant here, in this case, it is R while recessive allele is represented with small r. Both of these are used to represent color traits.  

Dominant allele = R

Heterozygous Red = Rr

Homozygous red = RR

Homozygous white = rr

Monohybrid cross = Rr × Rr

Monohybrid cross is the cross in which only one trait with two alleles are taken into account  

Recessive allele = r

Answer 2

From the punnet square it can be identified that,

R- dominant allele(red)

r- recessive allele(white)

Rr- heterozygous red

RR-homozygous red

rr-homozygous white

It is a monohybrid cross because it is a cross between paternal and maternal genotypes possessing a pair of contrast characters.
