Which of the following statements describes how human traits are inherited?

Children receive half of their genes from each parent.

Only dominant traits are passed from parents to their children.

Traits skip a generation, passing directly from grandparents to their grandchildren.

Female children receive genes only from their mothers, and male children receive genes only from their fathers

Which of the following is a reason for DNA replication in skin cells?

to enable the skin cells to make more proteins

A biological process is represented in the diagram. Which of the following concepts is BEST illustrated by the diagram?

crossing over creates new genetic diversity in gametes

mitosis increases the number of chromosomes in zygote cells

in asexual reproduction, the offspring produced are genetically identical to the parent

in sexual reproduction, the offspring receive the same number of chromosomes from each parent

1

a blood cell with 46 chromosomes

a sperm cell with 23 chromosomes

1

An egg cell in a gorilla contains 24 chromosomes. When the egg cell is fertilized, which of the following occurs?

The 24 original chromosomes replicate, resulting in 48 chromosomes in the fertilized egg.

The 24 original chromosomes split at the centromere, resulting in 48 chromosomes in the fertilized egg.

The nucleus of a sperm cell fuses with the nucleus of the original egg cell, resulting in 48 chromosomes in the fertilized egg.

The nucleus of another egg cell pairs with the nucleus of the original egg cell, resulting in 48 chromosomes in the fertilized egg
