Answer:
Hetezygous
Explanation:
<em>The genotype of the initial green pod plant would be heterozygous.</em>
Let pea pod color be represented by C (c) alleles.
First, let us assume that the genotype of the green pea pod plant is homozygous dominant, CC. This was crossed with homozygous recessive, cc.
CC x cc
Cc Cc Cc Cc
<u>All the progeny will have Cc genotype with phenotypically green color. </u><u>This is in contrast to the result obtained from the test cross in the illustration, hence the genotype of the initial green pea pod plant cannot be homozygous dominant.</u>
Now, let us assume that the genotype is Heterozygous, Cc.
Cc x cc
Cc Cc cc cc
<u>50% of the progeny has Cc genotype with phenotypically green color while the remaining 50% has cc genotype with phenotypically yellow color. </u><u>This is consistent with the result from the illustration.</u>
Hence, the genotype of the initial green pea pod plant is heterozygous.

Answer:
The organism is sterile because parts of the chromosomes in the zygote will only have a single set of chromosomes rather than the ideal pair. The arctic fox will produce gamates with 25 chromosomes (a single set) while the red fox will produce gametes with 19 chromosomes (another set). These gametes are supposed to fuse and have their chromosomes paired. However notice that the offspring will have (25 – 19) six (6) unpaired chromosomes. This means that during the formation of gametes in this hybrid offspring, there will be an issue in meiosis I which will result in nonviable gametes.
Answer:
Explanation:
during crossing over the two non-sister chromatids change their segments
and it results in genetic recombination which causes difference between parents and their offspring

I found this online:
Astronomers estimate the distance of nearby objects in space by using a method called stellar parallax, or trigonometric parallax. Simply put, they measure a star's apparent movement against the background of more distant stars as Earth revolves around the sun.
