Question

Due to Mendel's law of segregation
A)
homologous chromosomes pair up and cross over during prophase 1 of meiosis
B)
alleles belonging to the same gene will never end up in the same gamete during mitosis
C)
alleles belonging to the same gene will never end up in the same gamete during meiosis
D)
genes located on non-homologous chromosomes sort independently of one another during the formation of gametes

Answer 1

i chose B

Answer 2

@Abhisar

Answer 3

@Saylilbaby Are gametes ever produced by mitosis?

Answer 4

We produce gametes from specialized diploid cells called germ cells and the gametes, being haploid are produced by meiosis. Two gametes fuse to form the diploid zygote which then undergoes mitosis to produce daughter cells which also differentiate into different cell types.

Answer 5

@Saylilbaby Reread "B" carefully.

Answer 6

you mixed up mitosis and meiosis

Answer 7

D

Answer 8

@Saylilbaby It basically says that the alleles of a gene a separated during gamete formation, ending up in different gametes, and they are randomly united during fertilization.

Answer 9

so D

Answer 10

D is talking about multiple genes. We are talking about alleles of "a" gene.

Answer 11

C

Answer 12

Yep.

Answer 13

This is because the end product of meiosis are gametes with 1/2 the chromosome count as the mother cell. So, if there is a gene with two alleles you can see why it is impossible for a gamete to have both allele types.
