False.
In a stressful event, there will be a hormone released to the blood called adrenaline. Adrenaline hormone can prepare the body for fight or flight response. One of the effects of this hormone is making the muscle around hair called musculus arrector pili contracted. This contraction of the muscle is what causing the goosebumps. The decreased blood supply has no role in this event.
(B) 25% GG, 50% Gg, and 25% gg
<u>Explanation:</u>
Given:
Green is dominant and is coded by G
Albino is recessive and is coded by g
Two corn plants that are heterozygous for color are crossed.
The heterozygous condition of the plant would be Gg.
The cross is shown in the table attached.
According to the punnett square drawn,
The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)
= 25% GG , 50% Gg , 25% gg
Phenotypic ratio = 3 : 1 ( green : albino)
= 75% green, 25% albino
Answer:
They have contributed same allele for straight hair.
Explanation:
There are two conditions homozygous and heterozygous. In homozygous conditions both the allele of a particular gene is same in an offspring which means the offspring got two same alleles from its parent for a particular gene and if an offspring is heterozygous for a gene that suggests that the parent has contributed two different alleles for that gene in the offspring.
So If Micah is homozygous for straight hair then it can be concluded that his parents have contributed two same alleles for straight hair genes.
Have six months of this week I have a really busy busy time and I’m not gonna I’m going back home I have a really busy busy time and I’m not going back home to work I have to work on a week or so then I will be back at my appointment and I’ll be there at six
So: both parents' genotypes (concerning baldness gene) are the same: Bb. Possible genotypes of an offspring: BB, Bb, Bb, bb . bb means non-bald girl or boy. Bb means bald boy or non-bald girl. BB means bald boy or girl. there is 25% chance of conceiving a child with a genotype BB. But there is also 50% chance of conceiving a girl. So the answer is: 25% x 50% = 12,5%
