Eigure 3 combination during meiosis Recombination the exchan

Eigure 3 combination during meiosis: Recombination the exchange of DNA sequences between two chromatids given loci which result in single chromatids that contain both matemal and patemal DNA sequences Recombination occurs of Meoss (when the homologous chromosomes pairup) which takes place atter DNA replication and before Metaphase L in Figure 3 is not shown for simplicity.

Solution

a) genotype of germ cell is Aa
b) Since genotype is Aa; it has two different types of alleles which are A and a
c) Since it has one dominant and one recessive allele of same gene, it is heterozygous.
d) Genotype of gametes= A and a
e) Each gamemte will have one copy of chromosome 1.
f) Each gamete has one allele of gene 1
g) genotype A= 2 gametes/ 50%
gentoype a= 2 gametes/ 50%
h) The female germ cell will make two types of gametes; 50% having A and 50% having a.
