• What do homeobox genes code for in animals?

1 answer:

6 0

Homeobox genes contain a particular DNA sequence that provides instructions for making a string of 60 protein building blocks (amino acids) known as the homeodomain. Most homeodomain-containing proteins act as transcription factors, which means they bind to and control the activity of other genes.

A dihybrid cross is performed between plants that differ in two Mendelian traits: Stem length (T or t) and flower coloration (R

Dahasolnce [82]

Answer:

A. 3/16

Explanation:

The four possible outcomes for Stem length are:

Tt, tT, TT and tt.

The dominant trait (tall stems) will manifest itself in 3 out of 4 outcomes, so its ratio is 3/4.

The four possible outcomes for flower coloration are:

Rr, rR, RR and rr.

The non-dominant trait (white flowers) will manifest itself in 1 out of 4 outcomes, so its ratio is 1/4.

Multiplying both ratios gives us the ratio of offspring that have tall stems and white flowers:

$\frac{3}{4}*\frac{1}{4}=\frac{3}{16}$

Therefore, the answer is A. 3/16
