Answer:

Sex linked inheritance may be defined as the type of inheritance in which the trait or mutation is present on X chromosomes rather than on autosomes. Sex linked trait expression will depend upon the type of sex.

Two type of inheritance of sex linked trait are X linked dominant and X linked recessive trait. In X linked recessive trait, the male are more affected as they have only single X chromosome. Females should have both X chromosome affected for the expression of the trait. In sex linked dominant trait, a single X chromosome is enough for the expression of trait.

For example: Color blindness is an sex linked recessive trait, the mother generally passes the trait to their sons. Fragile X syndrome is a sex linked dominant trait in which the affected father will have all the affected daughter.

In garden peas, long stems are dominant to short stems, and yellow seeds are dominants to green seeds, too long/yellow pea plant
Lera25 [3.4K]

Answer:

A) 300

B) 3:1

C) 9 long yellow : 3 long green : 3 short yellow : 1 short green

Explanation:

Long stems (L_) are dominant to short stems (ll)

Yellow seeds (Y_) are dominant to green seeds (yy)

We interbred pea plants with long stems and yellow seeds (L_Y_), but they had a short green parent (llyy) that could have only produced <em>ly</em> gametes, so our plants are heterozygous <em>LlYy</em>.

C) We interbred them LlYy x LlYy. If the two genes are unlinked, this is a typical dihybrid cross and from Mendel's law of independent assortment we know that the offspring will have the following phenotypic ratios:

  • 9/16 L_Y_ (Long, yellow)
  • 3/16 L_yy (Long, green)
  • 3/16 llY_ (short, yellow)
  • 1/16 llyy (short, green)

A) 3/16 × 1600 = 300 plants will be long and green.

B)

9/16 + 3/16 = 12/16= 3/4 plants will be yellow;

3/16 + 1/16 = 4/16= 1/4 plants will be green.

The ratio will be 3 yellow : 1 green
