Answer:
Eukaryotes grow and reproduce through a process called mitosis. In organisms that also reproduce sexually, the reproductive cells are produced by a type of cell division called meiosis. Some eukaryotic organisms also reproduce asexually through processes such as budding, regeneration, and parthenogenesis.
Homozygous refers to having the same or identical alleles for a single trait.
So, your answer is YY or yy

Answer:
C. On average, 25% of the children are affected by the autosomal recessive disease if both parents are carriers.
Explanation:
A recessive trait is always expressed in homozygous genotype only. To have progeny with recessive traits from two normal parents, both the parents should be heterozygous carriers. For example, two normal parents with genotype "Aa" have 25% of the chances to have a child with homozygous recessive genotype (Aa x Aa = 1/4 AA: 1/2 Aa: 1/4 aa).
An autosomal trait is equally expressed in both males and females. Inbreeding increases the homozygosity and thereby, increases the risk of expression of recessive traits which are otherwise masked in heterozygous genotype.
