In pea plants, purple flowers are dominant over white flowers. The phenotype ratio of purple to white flowers in a population of five plants is 4:1. How many plants have white flowers?1

----------

In some lizard species, a short tail is recessive and a long tail is dominant. According to the principle of dominance:
a lizard with a TT genotype will have a short tail
a lizard with a tt genotype will have a long tail
a lizard with a Tt genotype will have a short tail
a lizard with a tt genotype will have a short tail

Answers

Answer 1

Answer: 1. 1
Since the ratio is purple flowers to white flowers, and the ratio is 4:1 out of 5 plants, there is 1 white flower. Remember that, in a ratio, the first number is the first one mentioned, and the second number is the second one mentioned.

2. A lizard with a tt genotype with have a short tail
Since the short tail is recessive, it can be represented with a lowercase letter (t), and since the long tail is dominant, it can be represented with a capital letter (T). Because the long tail gene is dominant, if even one capital T is present in a genotype, the lizard will have a long tail. You can label the different kinds of genotypes if it helps.

TT - long tail, since both genes are for a long tail
Tt - long tail, since one gene is for a long tail, and the long tail is dominant
tt - short tail, since both genes are for a short tail

Hope this helps!

Answers

In some animals that lay eggs, such as frogs, gastrulation is accomplished when the hollow blastula invaginates to form an inner layer of cells called the endoderm and an outer layer of cells called the ectoderm. ... These three layers, the endoderm, the ectoderm and the mesoderm, are called the primary germ layers.

A train is to cars as a molecule of DNA is to -------

Answers

Answer: Genes

Explanation:

The cars are the part of the train. This means that the genes are the part of the DNA.

The genes are the small components of the DNA. The functional unit of DNA are genes.

These genes are responsible for the characters that is transferred by DNA from one generation to another generation.

It can be said that the genes are the functional unit of DNA as Cars are the functional unit of train.

Your answer would be Genes.

Answer:

Under which condition would a mutation have the most impact on allele frequency?

There is gene flow

Explanation:

Mutation occur mostly during fertilization where there is gene flow and this makes it to have an impact on the allele frequency
