Answer:
4 gametes
The cells that enter meiosis II are the ones made in meiosis I. These cells are haploid—have just one chromosome from each homologue pair—but their chromosomes still consist of two sister chromatids. In meiosis II, the sister chromatids separate, making haploid cells with non-duplicated chromosomes.
Explanation:
Reduces water loss compared to other nitrogenous wastes but requires more metabolic energy to produce
Mammals excretes urea as the primary nitrogenous waste product. On the other hand birds, and reptiles excretes uric acid as the primary nitrogenous product. They are called uricothelics because they can convert ammonia to uric acid. Uric acid is a compound similar to purines. This is produced through a complex metabolic pathway thay cost high energy. However it has advantages such as reducing water loss.
<span>The answer is two. In incomplete dominance, heterozygotes have a trait that is intermediary between dominant and recessive homozygote. Let allele A be dominant and allele a recessive allele. The genotypes and phenotypes are as following: genotype: AA - phenotype: dominant homozygote with red feathers, genotype: Aa - heterozygote with purple feathers, and genotype: aa - recessive homozygote with blue feathers. In the cross of two purple birds (Aa x Aa), we have 1 bird with genotype AA and red feathers, 2 birds with genotype Aa and purple feathers, and 1 bird with genotype aa with blue feathers.</span>
