The diploid chromosomal number of a cat is 38. If one of the homologous chromosome pairs does not separate during Meiosis I, how

kow [346]

Answer:

25 and 21

Explanation:

if a homologous pair does not separate, then the homologous pair (when the spindle fibers are dragging it over to the other pole), then that chromosomes DNA will be the exact same as the paternal and maternals' DNA. During Meiosis I, there is the stage where the homologous pairs are lined up and pulled apart (where an exchange tends to happen), but if there pair doesn't mix, then the exact same DNA is duplicated, and thus, the same traits can be found in the daughter cell. If you are talking about an entire homologous pair being pulled over to one side of the nucleus, depriving the other side of a chromosomal pair, the daughter cells would then have 21 chromosomes, and the other one would have 25 chromosomes. The gametes, similarly, would have 21 chromosomes and 25 chromosomes.

In maize (corn) plants, a dominant allele I inhibits kernel color, while the recessive allele i permits color when homozygous. A

EleoNora [17]

Answer:

Phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio= 1:2:1:2:4:2:1:2:1

Explanation:

According to the given information, the dominant allele "I" is epistatic to P and p alleles and presence of "I" inhibits the expression of both "P" and "p" alleles.

A cross between two heterozygous plants for both locus would give the F2 progeny in 12 colorless: 3 purple: 1 red ratio.

Here, the F2 genotype with "I-G" and "I-gg" would produce colorless kernels while the ones with "ii-G-" would exhibit purple colored kernels. The F2 genotype "iigg" would beak red kernels.

Hence, the phenotype ratio= 12 colorless : 3 purple : 1 red

Genotype ratio would be same as for the mendelian dihybrid cross= 1 IIPP: 2 IIPp :1 IIpp: 2 IiPP :4 IiPp: 2 Iipp: 1 iiPP :2 iiPp: 1 iipp
