Explanation:
In addition, in meiosis I, the chromosomal number is reduced from diploid (2n) to haploid (n) during this process. ... In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23).
Answer: they are used to measure and keep things precise during constuction
Explanation: because if you watch videos and look up info and research it tells you about their jobs and what they use for their jobs
Answer:
false
Explanation:
These processes of breakdown and transport due to exposure to the environment are called weathering and erosion. Weathering and erosion affect all rocks on the earth's surface.
Answer:
1/8
Explanation:
An individual must have all three dominant alleles to be red, in homozygosis or heterozygosis (R_E_D_).
<u>The parental cross was:</u>
RREEDD x rreedd
F1: RrEeDd
<u>The test cross</u> is between the RrEeDd indiviudals and homozygous recessive rreedd.
The genes assort independently, so we can use Mendel's law of segregation to predict separately for each gene the proportion of the offspring that will have the dominant alleles.
<h3><u>Rr x rr</u></h3>
1/2 Rr
1/2 rr
<h3><u>Ee x ee</u></h3>
1/2 Ee
1/2 ee
<h3><u>Dd x dd</u></h3>
1/2 Dd
1/2 dd
Genes are independent, so the probability of having a R_E_D_ offpsring is calculated by multiplying the individual probabilities of having a dominant allele for each gene:
1/2 (Rr) × 1/2 (Ee) × 1/2 (Dd)= 1/8
