Question

question 8
which of the following expresses mendels law of segregation?
all dominant alleles of different genes divide into different cells from the recessive alleles.
the two alleles of a gene separate during meiosis and end up in different gametes.
when gametes form, the genes originally from one parent all end up in different gametes from the genes originally from the other parent.
gametes with recessive alleles will fuse only with each other.

Explanation:

Mendel's law of segregation states that during meiosis, the two alleles of a gene separate and end up in different gametes. This is a fundamental principle in genetics.

• The first option is incorrect as it refers to multiple genes and alleles in a way not related to the law of segregation.
• The third option is about genes from parents and not about the separation of alleles of a single gene (which is the focus of the law of segregation).
• The fourth option is incorrect as gametes with recessive alleles can fuse with gametes having dominant alleles.

Answer:

The two alleles of a gene separate during meiosis and end up in different gametes.
