The Correct choice is C

If plant's allele is tt, then it means that the plant got both short (recessive) allele from both parents.

Answer:

Both parents contributed a recessive allele.

Both parents were short.

this is because a recessive allele will only express itself in the absence of dominant allele

Answer:

A. Atmosphere

Explanation:

Atmosphere would be most immediately affected by a decrease in sunlight because sunlight is responsible for the photosynthesis in plants. if sunlight decreases, the photosynthesis reaction is also decreases in plants and less carbondioxide gas is used by the plant from atmosphere for making their food so we can say that atmosphere is greatly affected by the decrease in sunlight.

The following goal the U. S. Integrated Ocean Observing System (IOOS) is not intended to address is to promote ocean ownership.

<h3>What is the Integrated Ocean Observing System?</h3>

The United States' Integrated Ocean Observing System, is a network of people and technology.

It collaborates to collect and transmit data on our coastal waters, Great Lakes, and seas.

Two organisms, AABBCCDDEE and aabbccddee, are mated to produce an F1 that is self-fertilized to produce F2. If the capital lette

Galina-37 [17]

Answer:

a) How many genotypes will occur in F2

--The genotypes would be- AA Aa aa BB Bb bb CC Cc cc DD Dd dd EE Ee ee (15 genotypes)

Reason-

This is because, after crossing the parents, the F1 generation would all be Heterozygous dominant since one parent is homozygous dominant, while the other is homozygous recessive.

b) 25% of all F2 genotypes would be recessive across the 5 loci

Reason-

This is because each loci would produce only a 25% chance for a recessive trait, which would results to a general probability of 25% also.

c) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aaBBccDDEE

d) Yes i would change my answer in A and B if the parent cross was- AABBCCDDEE X aabbccddEE
