Which group below are all strategies male birds employ to avoid sperm competition?

Biology
1 answer:
ehidna [41]3 years ago
8 0
<span>Male adaptations to sperm competition include relatively large testes, large sperm stores and long spermatozoa, mate guarding and frequent pair copulations. Females show no obvious morphological adaptations to sperm competition but, by controlling whether copulations are successful, they probably determine its frequency and extent. Despite this, the evolutionary benefits females acquire from extra-pair fertilizations are poorly understood.</span>

A gene exists in two alleles, which we will call B and b. The gene is 1123 bp in length, and the B and b alleles exhibit single
Hitman42 [59]

Answer:

The below options will complete the question

Select one:

a. Gap repair synthesis

b. Mismatch repair

c. Direct repair

d. Nucleotide excision repair

Our answer is surely A.

a. Gap repair synthesis

Explanation:

Alleles of gene B differ by 6 bps and are seeming close to each other among the 1123 bp within the particular gene, favouring the gap repair synthesis.

In the gap repair synthesis, a double stranded break is formed at a homologous chromosome with a small part of the gene or the 6 bps of the recessive allele

being digested away.

Strand invasion and a D-loop formation is followed by the new region being occupied by the dominant B allele to yielding dominant B allele in both chromosomes.

The gap repair synthesis allows the 6bps to be converted to the dominant B from the recessive b when in proximity/being close together.
