What is the genotype of the parent with orange eyes and white skin? (Note: orange eyes are recessive.)B=black eyes G=green skinb
kykrilka [37]

Answer:

D

Explanation:

Two genes are involved in this case: one coding for eye color and the other for skin color.

According to the question, the allele for Black eyes (B) is dominant over the allele for orange eyes (b) while on the other gene, the allele for green skin (G) is dominant over the allele for white skin (g).

This means both alleles for orange eyes (b) and white skin (g) are recessive i.e masked by their counterpart allele

Since they are recessive, they will only be phenotypically expressed if they are in their homozygous state. i.e same type of allele.

In this case, the parent has orange eyes and white skin i.e.both recessive traits

Therefore, the genotype will be bbgg.

"A parakeet with green plumage is crossed to a white parakeet. The progeny are all green. Crossing these progeny together gave t
Galina-37 [17]

Answer: This is due to the theory of independent assortment of gene.

This means that gene separate and assort with each other, independently. There a gene that is recessive in the parents may not be recessive in the offspring.

A recessive gene is the gene that makes up the physical appearance of the offspring. While a dominant gene is the gene that exist in the offspring, but is not among the gene that makes up the physical appearance of the offspring.

For the two pure stock parent plants, their have yellow and blue as the dominant gene, while green and white are the recessive gene.

That's is why the yellow and blue gene has a tendency of occurrence in future generations.

For their first progeny which appears to be all green, is because the green gene has sorted themselves independently to be recessive, while others become dominant.

For the second progeny, the recessive gene from the parent plants which was carried by the offspring as dominant gene, now became recessive in some plants.
