Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes

<em>The question is incomplete. Please read below to find the missing content.</em>

<em />

Selection is usually strongest in the male of the species. D) because sperm are small and plentiful, while eggs are large and energy-rich.

Phenotype refers back to the observable traits of an organism as a multifactorial effect of genetic trends and environmental influences. The organism phenotype includes its morphological, biochemical, physiological, and behavioral residences.

A person's genotype is their specific collection of DNA. extra especially, this term is used to refer to the two alleles a person has inherited for a selected gene. Phenotype is the detectable expression of this genotype – a patient's clinical presentation.

The sum of an organism's observable traits is its phenotype. A key difference between phenotype and genotype is that, even as genotype is inherited from an organism's parents, the phenotype isn't.

Both intrasexual and intersexual selection usually cause changes in phenotypes for males and little changes in female phenotypes. Why is sexual selection usually strongest in the male of the species?

a. Males are naturally more aggressive

b. Males have a smaller genetic component than females due to fewer X chromosomes

c. Males do not pass on their mitochondria and therefore have more invested in each individual mating event

d. Because sperm are small and plentiful, while eggs are large and energy-rich.

Answer:

Looking at tibetan highlanders who thrive at high altitudes- normally that would make us sick- they have adapted, 60% oxygen- could pose huge health issue (live with 10% less oxygen in blood than us)
