In beans the pod texture and growth form genes are located on different chromosomes. There are two varieties of beans in a farme

irina1246 [14]

Answer:

a. Genotype in F1 - TtBb

Phenotype in F1 - tough pods, bush-type growth

b. Proportion of F2 that are heterozygous for bush-type growth form = 5/8

c. Proportion of the F2 with tender pods = 1/4

d. Proportion of F2 that are heterozygous for growth form and have tender pods = 1/8

Explanation:

Since the two traits are located on different chromosomes, they will independently assort during gametes formation. T is dominant over t and B is dominant over b.

Two true-breeding varieties were crossed at the beginning of the program:

TTBB x ttbb

All F1 plants will have the genotype TtBb with tough pods and bush-type growth form.

Advancing the cross to F2:

TtBb x TtBb

Progeny

1 TTBB - tough pods, bush-type

2 TTBb - tough pods, bush-type

2 TtBB - tough pods, bush-type

4 TtBb - tough pods, bush-type

1 TTbb - tough pods, climbing-type

2 Ttbb - tough pods, climbing-type

1 ttBB - tender pods, bush-type

2 ttBb - tender pods, bush-type

1 ttbb - tender pods, climbing-type

Proportion of F2 that are heterozygous for bush-type growth form = 10/16 = 5/8

Proportion of the F2 with tender pods = 4/16 = 1/4

Proportion of F2 that are heterozygous for growth form and have tender pods = 2/16 = 1/8

How is hair grown? give me a really really really detailed answer

Rainbow [258]

Hair grows out of little pockets in your skin, called follicles. Here's how it happens:

Your hair begins growing from a root in the bottom of the follicle. The root is made up of cells of protein.

Blood from the blood vessels in your scalp feeds the root, which creates more cells and makes the hair grow.

The hair gets pushed up through the skin as it grows, passing an oil gland along the way. The oil gland adds oil to the hair and keeps it shiny and soft. It can make it greasy, too. That's why you need to wash your hair.

The hair dies by the time it is long enough to poke out through the skin. Yes, hair is dead. That's why it doesn't hurt to get a haircut.

Hair on the rest of your body goes through this same process, but the whole cycle only lasts for a month or so. That's why body hair does not grow very long in length like the hair on your head does.

Here are some facts about follicles and your hair:

You are born with all of the follicles you will ever have — about 5 million.

You have about 100,000 follicles on your scalp, which is the skin on your head.

Hair grows very fast and male hair grows faster than female hair. The only part of your body that grows faster is bone marrow, the soft stuff inside your bones. The hair on your head grows about 6 inches a year. So, even though it's one of the fastest-growing things on your body, it takes a while to grow it really long.

Some follicles stop growing hair as you get older. This happens more in some people than in others. That's why some people get thinner hair when they get older, or go bald.
