Answer:

The punnet square can be completed as follows:

C C

A AC AC

The results from the punnet square show that all of the offsprings form will be agouti as agouti is the dominant trait. However, the genotype of the offspring will be heterozygous carrying the alleles AC.

A dominant trait is the trait which arises due to a dominant allele. The dominant allele masks the effect of the recessive allele.

A heterozygous genotype occurs when the alleles of a gene are different.

Answer:

One choice should be “exponential growth curve”, choose that. If you could post a pic of the remaining options, I'll try and solve it for you further.

In pea plants the allele for tall plants in dominant to the allele for short plants, and the allele for purple flower colour is

Tom [10]

Answer:

The correct answer is - 4. ttPp

Explanation:

Given - tall is dominant over short pea plant

let assume T is dominant and t is short which is recessive

Similarly, P for dominant purple flower and p for white flower

The offspring has a short plant which means it has both t allele or recessive allele for the height of a plant by the cross of a true-breeding purple and true-breeding white:

P P

p Pp Pp

This means the offspring would have a heterozygous case for the genotype of the flower of the pea plant

Thus, the correct answer is ttPp

a guinea pig with hair (HH) is breed with a guinea pig without hair (hh) what would the phenotype of their offspring be?

iren [92.7K]

Answer:

the genotype is (Hh) phenotype hybrid which is a Guinea pig with hair.( hybrid means its not a pureblood haired Guinea pig. pureblood means same. EX: (GG). Guinea pig with hair. its also known as heterozygous, and zygous.)

witch also means its heterozygous. there is no percentage chance for something to have a different genotype of phenotype.

When colorblind women married a male with normal vision, all their daughters have normal vision and all their sons are colorblin

worty [1.4K]

Answer:

X-linked recessive

Explanation:

The trait is a sex-linked trait because the daughters are not colorblind, but the sons are. We know this its recessive because the daughters have inherited the mother's X chromosome that has the colourblindness trait, but are not colorblind because the father's X does not have the colourblindness trait. The sons are colourblind because they inherited the X from their mother with the colourblindnese trait and a Y from their father. The colourblindness trait or normal vision trait is not carried on the Y, so the mother's X chromosome's trait is expressed.

Sorry if it's confusing i tried my best to explain it

ArbitrLikvidat [17]

Corticotropin-releasing factor is produced by the anterior pituitary, hypothalamus, adrenal glands, and ovaries. It is a hormone released in response to stress. Secretion has been seen to be higher in patients with depression and Alzheimer's disease. In addition to the aforementioned, CRF is secreted in lymphocytes and the placenta.
