A monkey has 42 chromosomes in almost all its cells. How many chromosomes are in a monkeys haploid cells?84
42
23
21

Answers

if 42 is a diploid cell, then a haploid would have 21

If the monkeys chromosomes are haploid cells it would be 21 because haploid also means "half".

The two types of cell cycle genes that, if mutated, cause cancer cells to divide uncontrollably are called tumor suppressor genes andA. growth factors.
B. proto-oncogenes.
C. cancer genes.
D. telomeres.

Answers

Answer:

The correct answer is option B. "proto-oncogenes".

Explanation:

Tumor suppressor genes and proto-oncogenes are two types of genes that can cause the development of cancer cells if they suffer a mutation. The main difference between tumor suppressor genes and proto-oncogenes is the way they cause cancer. If tumor suppressor genes are inactivated they produce cancer cells, while if proto-oncogenes are activated is when they produce cancer cells.

Tumor suppressor genes and proto-oncogenes cause cancer cells to divide uncontrollably.

The answer is B) proto-oncogenes.

What is the phenotype of a heterozygous person using T for tall and t for short

Answers

Sense the person is heterozygous, the person will receive one of each gene. Phenotype is what the person will look like. So sense T is for tall, this will be the dominant trait because it's capital, t is for short, and is less dominant. So the person's phenotype will be tall.

--Hope this helped.

Answer:

the phenotype is tall

Explanation:

T= dominant

t=short

the dominant always masks the recessive genotype

phenotype means the physical appearance of an organism, so it would be tall
