Dihybrid cross

What are the male and female sexual organs in pea plants called?

Male organs are called stamens and female organs are called carpals.

What is the F1 Generation in Mendel's experiments?

The hybrid offspring produced from crossing two true-breeding pea varieties.

What phenotypic ratio do Mendel's dihybrid crosses produce in the F2 generation?

A 9:3:3:1 ratio of phenotypes.

What traits were studied in Mendel's dihybrid cross?

Seed Colour (yellow dominant to green) and Seed Shape (round dominant to wrinkled).

What does Mendel's Principle of Independent Assortment state?

The alleles of different genes segregate independently of each other.

What happens when the F1 generation produces gametes according to Mendel's hypothesis?

Genes are packaged into gametes with all possible allelic combinations.

How many combinations are possible in the F2 generation from two traits?

16 combinations.

What are the distinct phenotypes resulting from Mendel's dihybrid cross?

Yellow-round, green-round, yellow-wrinkled, green-wrinkled.

What does Mendel's Principle of Dominance imply?

In a heterozygote, one allele may mask the presence of another.

What is the total number of combinations for 4 traits according to Mendel's principles?

256 combinations.
