in a 3-point cross, crossovers that occur during the formation of which gametes can be scored using the phenotype of f2 progeny?
JulsSmile [24]

In gametes generated by F1 tri-hybrids and gametes produced by parents from true-breeding populations.

When non-sister chromatids of homologous chromosomes exchange genetic material during meiosis, novel allelic combinations are created in the daughter cells. The locations of three genes in the genome of an organism are identified using a three-point cross. A homozygous recessive individual is crossed with a person who is heterozygous for three mutations, and the progeny's phenotypes are graded. When F1 progeny are self-pollinated, a 3:1 ratio of F2 progeny are created.

A maize plant with genotype Aa Bb produces the following gametes 100 Ab 45 AB 106 aB 50 ab This tells us that the two genes are
bogdanovich [222]

Answer:

True

Explanation:

The linkage relation of two genes can be determined on the basis of calculating recombination frequency.

If the recombination frequency value is greater than 50% then the genes are not linked and if the value is less than 50% then the genes are linked.

In the given question, the  crossover gametes formed will be Ab = 100

and aB= 106.

Therefore,

\dfrac{recombinant\ progenies}{ Total\ progeny}\times 100\\\\\dfrac{100 +106}{100+106+45+50}\times 100\\\\=\dfrac{206}{301}\times 100\\\\= 68.43\%

Since the recombinant frequency value is larger than 50% therefore the genes do not show linkage.

Thus, True is the correct answer.
