Having freckles is dominant (F). and not having freckles is recessive (f). a mother has FT and a father has Ft. if they have a child, which genotype will make their child not have freckles?

Answers

Answer 1

Answer:

Answer: A genotype Tt (f) will make their child not to have freckles. Only offspring with alleles containing the dominant gene 'F' will have freckles.

Explanation:

MENDEL'S PRINCIPLES OF INHERITANCE can be used to understand how genes and their alleles are passed down from one generation to the next.

The 3 principles include:

1. Law Of Dominance And Uniformity: Some alleles are dominant while others are recessive; an organism with at least one dominant allele will display the effect of the dominant allele.

2. Law of segregation: During gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene.

3. Law of independent assortment: Genes of different traits can segregate independently during the formation of gametes.

Answer 2

Answer: The father because of Ft

Which of the following choices is not evidence supporting the theory of plate tectonics?a. fossil assemblages
b. ancient cave drawing found in France
c. the jigsaw puzzle-like fit of the continents
d. traces of glaciation found in Africa and South America

Answers

Hi!
let's go through the options:

a. fossil assemblages

Imagine you find similar fossils in Africa and South America - it would tell you that the same animals lived on the same continents, suggesting that the continents were close together!
b. ancient cave drawing found in France - this only tells you that people used to live in France at the time the painting was created, not whether the continents moved - so this is the correct option!

c. the jigsaw puzzle-like fit of the continents

This jigsaw tells us that the continents likely moved so it's supporting the theory of tectonic movement

d. traces of glaciation found in Africa and South America
This suggests that those continents were previously somewhere else - that is, they moved! so again, it suggests the theory of tectonic movement

b. acient cave drawing found in france
