In two or more sentences, analyze why internal fertilization is more efficient than external fertilization?
almond37 [142]

Answer:

Although more offsprings are produced by the process of external fertilization but the process of internal fertilization is more efficient as compared to external fertilization. This is because, in external fertilization, it is more difficult for the sperm to find the egg and fertilize it. Even after fertilization, it might be that the zygote gets eaten up by a predator. There are none such risks in internal fertilization. The zygote is protected during the internal fertilization which makes this process more efficient.

An organism has a haploid number of 6. How many possible assortments of chromosomes are possible based on the independent assort
USPshnik [31]

Answer:

64

Explanation:

Assortment of chromosomes according to Mendel, is when alleles on the chromosomes get separated into gametes independenly of one another. Independent assortment reshuffles or rearranges the chromosomal pair in the resulting gametes. 2^n is a mathematical expression that can be used to determine the number of possible chromosome combinations, which n is the number of chromosomes that can be present in one gamete.

In this case, the organism has an haploid number of 6, meaning that 6 chromosomes can be present in the gamete. Hence, 2^6 will give rise to 64 possible combinations of chromosomes in each gamete.
