Use the punnett square below to answer the following questions r = round ears r= pointy ears 1 how many offspring will have round ears? what percentage of offspring will have 3pointy how many offspring will be carriers of the 4pointy ear based on the allele combination rr, both parents are considered to

0.75

0.26

0.5

Round ears dominant i think

I think for the first square its RR, second square Rr, third square Rr, and the fourth square rr. Usually they use uppercase for the dominant trait and lowercase for recessive so Im assuming number one would be abount 75%? the second one probably around 25% ns tho, Idk the last one But i hope this helps you, have a wonderul day/evening. :)

an individual’s sex (i.e., whether they are a male or female) is determined by the sex chromosomes. most people have two sex chromosomes, one that is inherited from their mother and one that is inherited from their father. typically, females have two x chromosomes (xx) and males have one x chromosome and one y chromosome (xy). conditions caused by changes (“mutations”) in genes located on the x chromosome are considered x-linked.

x-linked recessive inheritance

most x-linked conditions are recessive. this means that in a person with two x chromosomes (most females), both copies of a gene (i.e., one on each x chromosome) must have a change or mutation whereas in a person with one x chromosome (most males), only one copy of a gene must have a mutation. a female with a mutation in one copy of a gene on the x chromosome is said to be a “carrier” for an x-linked condition. a male with a mutation in a gene on the x chromosome is typically affected with the condition. because females have two copies of the x chromosome and males have only one x chromosome, x-linked recessive diseases are more common among males than females. however, x-linked recessive diseases can occur in both males and females.

for x-linked recessive disorders, an unaffected carrier mother who has a mutation in a gene on the x chromosome can transmit either the x chromosome with this mutation or a “normal” x chromosome to her children. if the father is unaffected, none of her daughters will be affected and all of her daughters will be unaffected—since they will inherit at least one normal x chromosome from their father. however, each daughter will have a 50% chance of being an unaffected carrier like her mother and a 50% chance of both x chromosomes being normal.

i believe it would be c: tons.
