cA cell in G1 of interphase has 12 chromosomes. How many chromosomes and DNA molecules will be found per cell when this original

Answer:

Prophase II meiosis-chromosomes-6 and 12 DNA molecules per cell.

Explanation:

Meiosis is a unique type of division that occur in cells in which the chromosome number is decreased to half with the creation of haploid cells. It can be referred to as reduction division and it mostly occurs in organisms which go through sexual reproduction.

In prophase II , the nucleoli and nuclear membrane disappear.

The chromatids reduces in length to become short and thick .

The centromeres migrates to the polar regions and set the spindle fibres in place for the second meiotic division.

Therefore, at Prophase II of meiosis

The daughter cells are haploid. Its haploid cells should possess six chromosomes and 12 DNA molecules.

A cross was made between a white male dog and two different black females. the first female gave birth to eight black pups, and
Svetradugi [14.3K]

In this case, the black body colour is the dominant one. The white dog is  homozygous recessive.

As the cross between the black female 2 and the white male results in all black pups. This means that the all the offsprings are heterozygotes and the Female 1 is homozygous recessive having a BB phenotype (where B codes for dominant allele).

As the cross between the black female and the white male results in four white and three black pups. This means that the all the black offsprings are heterozygotes, and the white ones are homozygous recessive and the Female 2 have a dominant and 1 recessive gene, and is a hetrozygotezygous recessive having a Bb phenotype (where B codes for dominant allele and b codes for recessive allele).
