Red-green colorblindness is an X-linked recessive trait. Neither John nor Ann is colorblind, but Ann’s father is colorblind. Wha
LiRa [457]

Answer:

To determine the fraction for the inheritance of Red green colorblindness the genotype of their parents must be considered although neither John nor Ann is color blind there is a very high probability that Ann will be a carrier if that is the case the fractions of the daughters of John and Ann that are expected to be carriers of that trait is 50% chance.

Explanation:

A punnet square can be used to determine any possible genotypic combinations in the parents. color  blindness is a recessive X-linked trait in which the patient is not able to distinguish, red or green or blue color. The normal gene and its recessive allele are carried by X chromosome in men, this color blindness appears in the presence of a single recessive gene Whereas in women color blindness occur only when both chromosome carry the gene this shows criss cross inheritance

The germ cell has 2 sets of chromosomes, and the four gametes will each have one set of chromosomes. ​​​​​​​ To have enough DNA
ICE Princess25 [194]

Answer:

This question lacks options, the options are:

A. Halved

B. Doubled (x2)

C. Quadrupled (x4)

D. Octupled (x8)

The answer is B.

Explanation:

Via the process of meiosis, gametes are formed in order for sexual reproduction to occur. However, the chromosomal content of the gametes are reduced by half. According to this question, a germ cell is said to have 2 sets of chromosomes i.e. diploid, meaning that each daughter cell after meiosis will have one set of chromosome (haploid, n).

However, before any form of division can occur, the DNA (genetic material) of the cell must be replicated i.e. doubled in order to ensure that each resulting gamete has enough chromosomes. This is applicable in this question as well as the DNA in the germ cell must be DOUBLED (×2) via replication in order to have enough DNA for each gamete.
