If a female fruit fly heterozygous for red eyes (XRXr) crossed with a white-eyed male (XrY), what percent of their offspring wou

Crazy boy [7]

Answer:

50%

Explanation:

Hello!

We can observe that:

R red eyes

r white eyes

The possible gametes for the female are XR and Xr.

The possible gametes for the male are Xr and Y

Xr Y

XR XRXr XRY

Xr XrXr XrY

The expected offspring is:

a red-eyed female (XRXr)

a red-eyed male (XRY)

A female with white eyes (XrXr)

A white-eyed male (XrY)

To check whether Earnest and Denise could have a baby with Type O blood, draw a Punnett square for a father who has blood Type A

Nutka1998 [239]

Answer:

Answer is explained below and also see the document attached below for Punnett square.

Explanation:

ABO blood type (A, B, AB, or O) is based on the presence (or absence) of the A and B antigens in the red blood cells. The blood type, A has only the A antigen (and has anti-B antibodies) while the blood type, B has only the B antigen (and had anti-A antibodies). Also in the AB blood type, both A and B antigens are present (but has no antibodies) while in the O blood type, both A and B antigens are absent (but has both antibodies).

The blood type is inherited from the parents and the offspring inherits one of the two alleles from each parent. The ABO blood type has three types of alleles: IA, IB, and i. Here, I is a term for antigen (isoagglutinogen).

The IA and IB alleles are dominant while the i allele is recessive. The blood type A is formed by either two IA alleles (IA IA ) or IA i. So, the genotype of blood type A is IA IA or IA i. The blood type B is formed by either two IB alleles (IB IB ) or IB i. So, the genotype of blood type B is IB IB or IB i. The O blood type is formed only by two i alleles (ii). So, the genotype of blood type O is ii. The IA and IB alleles (IA IB) give the AB blood type, which is an example of codominance (the traits of both the alleles are visible in the phenotype). The genotype of blood type AB is IA IB.

If the parents have blood type A and B, then they can have an AB blood type offspring. If the parents have blood type A and B and they both are heterozygous (IB i and IA i), then they can also have a O blood type child.

Here, the father has blood Type A (IA i genotype) while the mother has blood Type B (IB i genotype). Both the parents are heterozygous (IB i and IAi), so the possible genotypes of their child are IA IB (blood type AB), IA i (blood type A), IB i (blood type B) and ii (blood type O).

i.e., Blood Type Genotype

A IA IA or IA i

B IB IB or IB i

AB IA IB

O ii

maxonik [38]

Answer:

An experimental group is a group that receives the variable being tested in an experiment. The control group is the group in an experiment that does not receive the variable you are testing.

Explanation:

Control group, the standard to which comparisons are made in an experiment. ... A typical use of a control group is in an experiment in which the effect of a treatment is unknown and comparisons between the control group and the experimental group are used to measure the effect of the treatment.

The control group would be the group you keep control as you would not change anything about it throughout the course of the experiment. The experimental group you would give the experimental drug to.
