Answer:
Explanation:
A heterozygote advantage describes the case in which the heterozygous genotype has a higher relative fitness than either the homozygous dominant or homozygous recessive genotype. The specific case of heterozygote advantage due to a single locus is known as overdominance. Overdominance is a condition in genetics where the phenotype of the heterozygote lies outside of the phenotypical range of both homozygote parents, and heterozygous individuals have a higher fitness than homozygous individuals.
Answer:
A) XX
Explanation:
Each human cell is diploid (2n) and possesses 23 pairs of chromosomes. Out of 23 pairs, 22 pairs are autosomes and 1 pair is sex chromosomes. Sex chromosomes are designated by alphabet X and Y. In human females, each cell has two XX chromosomes, whereas males have one X and one Y sex chromosome.
Answer:
1. 2 red: 2 purple
2. 2 red: 1 purple: 1 white
Explanation:
For this question, you need to create two separate punnett squares. The first punnett square would have C^R over one square with C^P in the square next to it, and on the other side would C^P next to one square and C^W next to the square below it. It doesn't matter what side you put the alleles on, just make sure the same alleles of the same flower are on the same side. Then, in order to find the phenotype, or in this case the color of the flowers' offspring, follow the dominance rules the question gave you. Remember, alleles don't have to be homozygous to determine what color they will be. Just make sure that the dominant allele is the allele used to determine the color. The same rules will apply for the second punnett square, and then you should get your answer. Hope this helps! :)
