Biology

Klio2033 [76]3 years ago

He first step in solving this problem requires an examination of the possible genotypes of the parents. As stated color-blindness is a recessive linked trait. So the genotypes of the parents should be:

<span>mother's genotype (normal vision but whose father was color blind) XNXn</span>

She is a carrier because of her heterozygous condition. For the recessive gene to be expressed one must be homozygous for it.

<span>father's genotype (color blind) XnY</span>

<span>
</span>

During the second and third trimesters of
Verizon [17]

Answer:During the second and third trimesters of

gestation androgenic C19 steroid, and dehydroepiandrosterone sulfate (DHEA-S), are secreted by the fetal adrenal gland and human placental lactogen (hPL), is secreted by the placenta.

Explanation:During midgestation, the fetal zone occupies 80–90% of the cortical volume and produces 100–200 mg/day of the androgenic C19 steroid, dehydroepiandrosterone sulfate (DHEA-S), which is quantitatively the principal steroid product of the primate fetal adrenal gland throughout gestation. While human placental lactogen (hPL) may be secreted preferentially into the fetal circulation, exerting growth-promoting effects at a time when the rate of linear growth of the fetus is maximal.

In a population, natural selection acts on
Bess [88]

Answer:

<em>In a population, natural selection acts on phenotype  of individuals.</em>

Explanation:

Natural selection tends to favour those organisms of a population which carry traits that allow them to be better adapted to the environment and these traits are passed on to their offsprings. Natural selection tends to act on the phenotype of the population whereas evolution is the phenomenon which changes the allele frequencies. Natural selection acts on individual organisms of a population whereas the change in populations, on the whole, arises due to evolution.
