Question

For each of the following individual genotypes, list the gametes the parent could produce. Indicate whether each genotype represents a homozygous or heterozygous individual. Assume each letter (A, B, C… ) references a different trait. Capital, lower case, letter with a prime sign (R’) or other different variants of the same letter indicate differing forms (alleles) for a given trait.

Genotype	Homo/heterozygous	Possible gamete	Possible gamete (if different from the first gamete
WW
Tt
gg
Rr
RR

Answer 1

The correct answers are as follows :-

Genotype	Homo/ Heterozygous	Possible gamete	Possible gamete (If different from first gamete)
WW	Homozygous	W	_
Tt	Heterozygous	T	t
gg	Homozygous	g	_
Rr	Heterozygous	R	r
RR	Homozygous	R	_

Homozygous :- An individual with identical copies of alleles of a particular gene.

If both the alleles are dominant then it is caled as Homozygous dominant such as WW and if both the alleles are recessive then it is called as Homozygous recessive for example gg.

Heterozygous :- An individual with one of each type of allele, one dominant and one recessive. For example Tt or Rr.

Gametes are haploid cells, and each cell carries only one copy of each chromosome.

Individual with Homozygous genotype can generate two two types of gametes since one allele is dominant and the other allele is recessive. Whereas in case of Homozygous individuals only one type of gamete will be there.
