[ANSWER]Genetics: Week 1 Assignment

TASK DESCRIPTION Genetics Week 1

1. Describe the stages of the cell cycle, including the 3 interphases and 2 mitotic phases

2. Assume you start with a cell that has 2 pairs (4 chromosomes) of chromosomes in it. Use colored pencils to draw the arrangement of chromosomes during meiosis. Describe the DNA content of the daughter cells you draw compared to that of the parent cell.

3. Cystic fibrosis (CF) is a genetic disease caused by a recessive allele, and the phenotype appears only in the homozygous recessive genotype (cc). A child was born with this disease from parents who do not have CF. Explain the genotype of the parents and the child. What is the probability that the child’s sibling from the same parents will also have the disease? (Show your answer with a Punnett square.)

4. Allele T (tall) is dominant over t (short) allele. Allele R (red flower) is dominant over r (white flower). How many different types of gametes can it generate if a plant has genotype TtRr? What are the gametes? If the plant does self-pollination, what is the phenotypic ratio in the next generation? (Show your answer with a Punnett square.)

5. Define genotype and phenotype. Explain why the same phenotype could have different genotype.

[Genetics Week 1 ANSWER PREVIEW]

The parent cell has four chromosomes where one pair is identical since it would be from one parent and would be different from the other one since the mother or the father have different chromosomes. During meiosis, the four chromosomes bond identically and then there is exchange and fusion of specific arms of the,,,,[Buy Full Answer for Just USD 9: 583 WORDS]
