What happens during Meiosis?

The cell splits itself twice to create 4 haploid daughter cells.

When the heterozygous genotype displays a DIFFERENT phenotype than the homozygous dominant and homozygous recessive

It is displaying incomplete dominance.

What is something Mendel did NOT learn from his experiments?

Pea plants with green pods taste better than plants with yellow pods.

What did the Blended Inheritance Theory suggest would happen when a black rabbit mated with a white rabbit?

A black and a white rabbit would produce grey rabbit offspring.

Which best describes Mendel's first law?

What happens during Meiosis?
The cell replicates itself to create 2 diploid daughter cells.
Two sex cells meet and the egg becomes fertilized.
The cell grows and releases a single diploid egg or sperm cell.
The cell splits itself twice to create 4 haploid daughter cells.

When the heterozygous genotype displays a DIFFERENT phenotype than the homozygous dominant and homozygous recessive
It is mutated.
It is displaying codominance.
It is classified as a different species.
It is displaying incomplete dominance.

A cross between two different colored TRUE BREEDING flowers (AA x aa) will result in a PHENOTYPIC ratio of
1:1 - 50% blue, 50% white.
9:3:3:1 - 56% blue, 19% purple, 19% mixed, 6% white.
3:1 - 75% blue, 25% white.
1. - 100% blue.

What is something Mendel did NOT learn from his experiments?
The genotypic ratio of an AA x aa cross is 100% Aa.
Alleles of a given locus separate into different gametes during Meiosis.
The phenotypic ratio of an Aa x Aa cross is 3:1.
Pea plants with green pods taste better than plants with yellow pods.
5
What is NOT one of the traits Mendel tested in his crosses?
Flavor
Pea Color
Pod Color
Flower Color
6
An organism with a diploid number of 2n will have a haploid number of n.
False
True

A gamete is also known as a sex cell, or a sperm/egg cell.
True
False

What did the Blended Inheritance Theory suggest would happen when a black rabbit mated with a white rabbit?
A black and a white rabbit could not produce any viable offspring.
A black and white rabbit would create cow-spotted offspring (B+W spots.)
Male rabbits would always look like their dads and females like the mom.
A black and a white rabbit would produce grey rabbit offspring.
9
Which best describes Mendel's first law?
The dominant allele from each gene pair will be donated to the gametes.
Both alleles from each gene pair will be donated to the gametes.
Alleles from a gene pair separate during gamete formation.
Both alleles merge into one allele that is donated to the gametes.
