Answer:
B) 1/2 X 1/2 = 1/4
Explanation:
It happens when both the parents are heterozygous for the trait. The cross related to this result is shown as under:
Father Mother
Bb x Bb
/ \ / \
Gametes: B b B b
| | | |
Probability: 1/2 1/2 1/2 1/2
The probability of formation of 'b' gamete from father is 1/2 because there are only two gametes 'B' and 'b' and out of these two one will be assorted as 'B' and another one as 'b' and from mother also the probability of formation of 'b' gamete is 1/2.
Now the assortment of gametes with each other is an independent event i.e. any gamete from father can fuse with any gamete of mother so the overall probability of formation of 'bb' genotype will be 1/2 x 1/2 = 1/4.
It represents the dominance.
<span>The dominance occurs when an allele (dominant) that is expressed in an organism’s phenotype, masks the effect of the recessive allele that is also present. In this case allele for brown coat color (F) is dominant to the allele for white coat color (f). When these two alleles are together (genotype is Ff) the brown color will be expressed as a phenotype.</span>
Answer:
Polygenic trait
Explanation:
A polygenic trait is a type of trait whose phenotype observed is affected by more than one genes i.e expression of the trait is controlled by not only a single gene but many. These traits include height or skin color and they display that display a continuous distribution; the hair color is controlled by 7 genes as described which is more than more.
Answer: more out of us
Explanation:well we breath 21 % of oxygen so that means their is more out of us
