Explanation:
species that lacks the variation necessary to adapt to a changing environment is most likely to become EXTINCT
Answer:
Yy, Yy, Yy, Yy
Yellow in color
Explanation:
Let the allele for green seed be represented by "y" and the allele for yellow seed be represented by "Y"
Given Yellow seed color is dominant over green.
Genotype of true breeding green seed parents will be yy
Genotype of true breeding yellow seed parents will be YY
F1 cross
Genotype of all the offspring is heterozygous "Yy"
Phenotype of all the offspring is yellow
<h2>Answer:</h2>
When the crossing over results in both mutant alleles on one chromosome and the other chromosome will be mutation free.
<h3>Explanation:</h3>
During the meiosis chromosomes are present in homologous form in a pair.
They exchange their genetic material with each other. This exchange is random and usually genetic material on the ends/telomere changes with the homologous chromosome.
In given condition the exchange is in such manner that the mutant allel of one chromosome shifts to other during crossing over. While other chromosome also contains its own mutant allele and does not exchange it during crossing over.
Answer:
It contains only about an eighth of our sun's mass. Faint red Proxima Centauri is only 3,100 Kelvin (5,100 degrees F or 2,800 C) in contrast to 5,778 K for our sun. So Proxima is 500 times less bright than our sun.
