Oduvanchick [21]

The provided question is incomplete as it lacks the combinations of parent as metion in the question, however the complete question is attached as the image.

Answer:

There are two parent combinations that are :

1. heterozygous black Ff cross with heterozygous black Ff

2. heterozygous black Ff cross with white ff

Explanation:

1. in first combination the each parent will produce F and f gametes, as it is shown as Capital F so it will be dominant over f as per the rule. so the cross can be shown as :

    F      f

F  FF    Ff

f  Ff     ff

where, FF are black Ff black and ff white offspring. As there is clearly 3 black offspring over one white spring so the ratio is 3:1 or 75% chances of black and 25% chances of white offspring (phenotype).

2. in second combination there would be F and f gametes for black parent and f and f for white parent, thus the offsprig would be :

    F     f

f   Ff    ff

f   Ff    ff

As, there is two black and two white springs are produced than the ratio would be 2:2 or 50% chances of each white offspring and black offspring (phenotype)

What role do genes and chromosomes play in the hereditary process?
uysha [10]

Each gene occupies a specific position on a chromosome. Because genes provide instructions for making proteins, and proteins determine the structure and function of each cell in the body, it follows that genes are responsible for all the characteristics you inherit. These pair up to make a total of 46 chromosomes.
