Answer:
1/2 or 50%
Explanation:
This question involves a single gene coding for the number of digits per paw in cats or humans. The allele for polydactyly i.e six digits (P) is dominant over the allele for normal number of digits i.e 5 (p).
According to this question, If a man who is heterozygous (Pp) for this trait marries a woman with 5 fingers (pp), the following gametes will be produced by each parent:
Pp : P and p
pp : p and p
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Pp, Pp, pp and pp
The offsprings with genotype Pp will have polydactyl, hence, the chances that they will have a child with polydactyly is 1/2 or 50%.
Neon is a non-reactive gas, because it <span>has a full outer energy level and does not wish to lose or gain any electrons. (Solution:B) Non-reactive gases have filled outer shells and </span>form no significant compounds. The electron configuration of the gas is responsible for the reactivity of the gas. The <span>electron orbital of the Neon that is filled with eight electrons.</span>

D= nucleic acids and fatty acids.DNA
Answer:
The purpose of meiosis is to produce gametes, which are used for sexual reproduction.
The cell reduces its chromosome number in half via a series of complex events. These events are summarised into two main groups: Meiosis I and Meiosis II, with each group encompassing several different events.
One way is : 1) Meiosis; the end product is 4 genetically different haploid cells.
Explanation:
Gametes are haploid cells that have only one set of chromosomes. As opposed to Somatic cells which contain two sets of chromosomes (these are known as diploid cells).
In Meiosis I, crossing over occurs during the event known as Prophase I. Crossing over is the process where non-sister chromatids exchange genetic information with one another. The site where this occurs between the chromatids is known as the chiasma.
