Consider the following food chain: garden plants are eaten by snails, which are eaten by birds, which are eaten by the household
SIZIF [17.4K]
The garden plants and snails stay balanced as they are still being eaten. However, if the cat is removed, the birds will overpopulate and then the snail would be eaten and decrease faster which gives garden plants an increase in population due to the decrease in snails. Hope this helps!

"Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely
lyudmila [28]

Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"

A) complete dominance

B) incomplete dominance

C) codominance

D) epistasis

E) incomplete penetrance

Answer:

B) incomplete dominance

Explanation:

Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.

For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".
