Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)
Gametes: (Ar, ar) and (AR, Ar, aR, ar)
F1 (Punnet square)
----|----- AR ------|------- Ar ------|------ aR -----|----- ar
Ar | AARr (gray) | AArr (yellow) | AaRr (gray) | Aarr (yellow)
ar | AaRr (gray) | Aarr (yellow) | aaRr (black) | aarr (cream)
Ratio: 3/8 yellow : 3/8 gray : 1/8 cream : 1/8 black
So the organisms could be classified in the same animal families
False! Climate change
The Earth used to be way colder than it is today
Answer:
A gene is a section of a chromosome that codes for trait.The specific combination of alleles an organism has is called its genotype which affects the organisms features.
Explanation:
A mutation in DNA affects the entire protiens synthesis process by producing the incorrect amino acids in the wrong places, causing issues with the ability of the organism to survive depending on what the protein is in charge of.
