Answer:
Maybe B, I need more evidence
Explanation:
Answer:
2nd one. Albedo and positive
Explanation:
The only possibility of the daughter being colour blind is where both parents have a recessive gene for colour blindness with the father being colour blind as well. so assuming the recessive allele is Xc, then the genotype of the mother is XCXc, where she has a normal colour vision and the father's genotype is XcY, where he is colour blind.
Answer:
25% of the heterozygous cross are short, and the offspring of a homozygous dominant and homozygous recessive pea plant will always display the dominant trait (phenotype), because they are heterozygous.
Explanation:
In this explanation, I'm assuming that the allele "T" for tall plants is dominant to the allele "t" for short plants, like in Gregor Mendel's pea plant experiment.
A homozygous tall pea plant will have the genotype "TT" and a homozygous short plant will have the genotype "tt" because homozygous means that both alleles are identical. Since "T" is dominant over "t", any plant with at least one "T" allele will be tall (the dominant trait), regardless of what the other allele is. Let's look at a Punnett square for this cross:
