Answer:
50%
Explanation:
According to the given information, the woman has normal BRCA alleles while the man carries one copy of the mutated BRCA allele (BRCA1). A diploid organism such as human beings can have two BRCA alleles. A child gets one BRCA allele from the mother and the other from the father.
The child of the couple would get one normal allele from the woman. However, with respect to the BRCA allele, the man would form two types of gametes in equal proportion. The 50% of his gametes would have the mutated BRCA1 allele while the rest 50% would carry the normal BRCA allele. Therefore, the man can transmit either normal or mutated BRCA allele to the child. So, there are 50% chances for the child to get the mutated allele.
Explanation:
<u>C. A red allele is present on both homologous chromosomes</u>
<u></u>
Homologous chromosomes are pairs of chromosome of similar lengths, banding patterns, and centromere positions, with genes at the same loci. For dominance, gene copies are present on both of the chromosomes; the dominat variant overrides the effect of the other recessive allele.
Further Explanation:
DNA molecules contain chromosomes that may have different forms called alleles. DNA, which is the genotype, is transcribed into mRNA and later translated into amino acids which are connected together by rRNA to form proteins which constitute the phenotype of an organism. DNA sequence mutations form new alleles, impacting the associated mRNA, and thus the encoded protein.
Homozygous individuals have a chromosome containing two variants of the same allele. Dominant homozygous individuals bear two copies of the dominant allele, whereas recessive homozygous individuals hold two copies of the recessive allele.

Answer:
It is important for scientists to study other planets because <u>it helps them learn more about Earth's history.</u>
<u></u>
Explanation:
In the expanse of the space-time continuum of the universe there are many celestial bodies from stars to planets that all formed at different times hence have different ages and are at different stages of formation.
Studying other planets helps reveal alot about our own planet, its history and its formation. By observing younger earth-like planets, scientists could understand how the earth looked like in its younger years and how it was formed.
