Question

When a green seeded pea plant with the genotype Gg produces gametes, what will be the genotypes of gametes?
a) all will be Gg
b) half will be GG, and half will be gg
c) All will be GG
d) Half will be G, and half will be g
e) they will be either all G or all g

Answer 1

The answer is (a) all will be Gg

Answer 2

Genotype of gametes produced by green seeded pea plant with Gg genotype

Explanation:

Correct Option: (d) Half will be G, and half will be g

The genotype of the green seeded pea plant is Gg.

This depicts that this green seeded pea plant is heterogametic. This pea plant has resulted from the cross over of homogametic GG and gg pea plants.

GG genotype indicates: Green seeded plant with dormant gene.

gg genotype indicates: yellow seeded plant with recessive gene.

Cross over of these two plants results into the formation of plant with Gg genotype.

This plant when going for meiosis for gamete production, will produce two types of gametes:

G genotype gametes: they will be half of the total gametes produced.

g genotype gametes : they will be half of the total gametes produced.

Gametes are always haploid in genetic content.
