Answer:
D) 38
Explanation:
Most eukaryotes use meiosis as a type of cell division to produce reproductive cells, also known as gametes, this cells are used for sexual reproduction where they fuse together in a process known as fertilization. Somatic cells are diploid while gametes are haploid.
Diploid = 2 (n)
Haploid = n
If the gametes are haploid and contain 19 chromosomes (n= 19), somatic cells must have twice the number (2 * 19 = 38). Options A, B or C are not possible be.
Answer:
AA, Aa and aa genotypes will be produced.
Explanation:
If two birds with AA and aa genotypes are crossed, 4 offspring with Aa phenotype may be produced in F1 generation.
P generation: AA x aa
/ \ / \
F1 generation: Aa Aa Aa Aa
When these F1 generation birds will be allowed to breed, the genotype of the F2 offspring will be as under:
Aa x Aa
/ \ / \
F2 generation: AA Aa Aa aa
3 types of genotypes AA, Aa and aa will be produced in F2 generation. Their ratio will be AA : Aa : aa = 1 : 2 : 1.
