The main difference between haploid cells and diploid cells is diploid cells have two complete sets of chromosomes, while haploid cells only have one complete set of chromosomes.
The answer to number 1 is d since asexual reproduction is how plants mate.
Answer:
Considering that white eyes are a recessive trait in flies, it is possible for two red-eyed flies to have offspring with white eyes only if both are heterozygous for this trait.
Explanation:
For two individuals with dominant phenotype for a trait to have offspring with the recessive trait, both must have a heterozygous genotype.
In the case of the characteristic eye color of the flies
:
- <em>Red eye (R) is dominant trait.
</em>
- <em>White eyes (r) is the recessive trait.
</em>
When both parents are heterozygous, their genotype is Rr
In Punnett Square it can see the result of the crossing of these individuals:
Punnett Square
:
<em><u>Rr X Rr
</u></em>
<em>Alleles R r
</em>
<em>R RR Rr</em>
<em>r Rr rr</em>
In the offspring, the probabilities are:
- 50% heterozygous individuals Rr, with red eye phenotype.
- 25% pure dominant individuals RR, with red eyes
- 25% individuals with the recessive rr genotype, white eyes.
<u>This is the possibility of two red-eyed flies having white-eyed offspring</u>.
