Explanation of Solution

Pictorial representation:

The following figure represents the cross between (D Opd op×d opd op).

Genetics, Chapter 7.2, Problem 22AQP , additional homework tip 1

Fig. 1: The cross between (D Opd op× d opd op).

The cross in “Fig. 1” is between the homozygous recessive parent and heterozygous dominant parent. In this cross coupling will occur because of heterozygous dominant parent. In this two alleles are present on a same chromosome, so this lead to the production of four gametes.

Recombination frequency is 0.07 centiMorgan, so the parent frequency is (1−0.07)= 0.93 centimorgan and for each parental gamete (0.932)= 0.465, and for recombinant gamete (0.072)= 0.035. In homozygous recessive parent neither coupling nor repulsion takes place because it will produce only one type of gamete with 100% recombination frequency.

Explanation of Solution

Pictorial representation:

The following figure represents the cross between (D Opd op×d opd op).

Genetics, Chapter 7.2, Problem 22AQP , additional homework tip 1

Fig. 1: The cross between (D Opd op× d opd op).

The cross in “Fig. 1” is between the homozygous recessive parent and heterozygous dominant parent. In this cross coupling will occur because of heterozygous dominant parent. In this two alleles are present on a same chromosome, so this lead to the production of four gametes.

Recombination frequency is 0.07 centiMorgan, so the parent frequency is (1−0.07)= 0.93 centimorgan and for each parental gamete (0.932)= 0.465, and for recombinant gamete (0.072)= 0.035. In homozygous recessive parent neither coupling nor repulsion takes place because it will produce only one type of gamete with 100% recombination frequency.

Fig. 2: The cross between (D opd Op×d opd op)

The cross in “Fig. 2” is between the homozygous recessive parent and heterozygous dominant parent. In this cross repulsion will occur because of heterozygous dominant parent. In this one allele is dominant and one is recessive, and both are present on a same chromosome, so this lead to the production of four gametes.

Recombination frequency is 0.07 centiMorgan, so the parent frequency is (1−0.07)= 0.93 centimorgan and for each parental gamete (0.932)= 0.465, and for recombinant gamete (0.072)= 0.035.
