In humans, the abo blood type is under the control of autosomal multiple alleles. color blindness is a recessive x-linked trait. mom is type a and is color-blind. dad is type b and has normal vision. they have a daughter who is type o and has normal vision. what is the probability that their next child will be a son who is type ab and is color-blind? enter your answer as a fraction (for example: 1/5).

1/8

Explanation:

The alleles that control the blood type are autosomal. The A and B alleles are codominant, and they are both dominant over the i allele.

The possible genotypes that determine the blood types are:

Color blindness is a recessive X-linked trait. The possible genotypes and phenotypes are:

The mom is type A and color-blind. She is and could be either or .

The dad is type B and has normal vision. He is and could be either or .

Because the daughter is type O, her genotype for blood type is ii. That means that both parents must have the recessive i allele. The mom is and the dad is .

To calculate the probability of having a type AB color-blind son, we need to do the Punnett Square (see attached image) and the rules of probability.

Given two independent events, the rules of probability state that the probability that both events occur is found by multiplying the probabilities of each event.

P(A and B) = P(A) x P(B)

Genes in different chromosomes assort independently, so the probability of having offspring with the genotype , is:

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;

the correct answer in apex is tissue development, i know because i just had this question
