I'LL MAKE YOU BAINLIEST IF YOU ANSWER Suppose a mother is a carrier for an X-linked recessive disorder such as hemophilia. Complete the Punnett square to model the heritability of this trait. Then, answer the question below.

1. What are the chances of a female carrier being born from these parents?

A.

0%

B.

25%

C.

75%

D.

100%

25%

Explanation:

If we don't have any information about the father's genotype, we have to make two different Punnett squares with the genotypes available. He can either be dominant or recessive, so the options are X^a or X^A. When we set up the Punnett square, we put Xa and XA for the mom's genotype and Xa for the dads genotype (since we're looking for females, we don't write his Y alleles) For that Punnett square, we get 1/2 or 50%. But, there's still another possible genotype for the dad, XA. So now we make another Punnett square with XA as dad and XA Xa for the mom. We again get 1/2 or 50%. If you have two different fractions for the probability, or likelihood of an event occurring, you multiply them together! So 1/2 times 1/2 is 1/4!

If we do know the dad's genotype, let me know because then I messed this up. Hope this helped, it helped me for my test on it tomorrow!

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and colour.

explanation:

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.
