In humans, to fold the tongue is a dominant trait (L), and the straight tongue is the recessive trait. What are the probabilitie
kaheart [24]

The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case:

1. dominant parent and recessive parent

2. heterozygous parents

Answer:

1. dominant parent and recessive parent:

dominant parents can be represented by LL and recessive parent is represented by ll, so the gametes would be L, L and l, l.

so,

 L    L

l  Ll   Ll

l  Ll   Ll

so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue.

2. heterozygous parents

In this case, parents have Ll genotype and gametes would be L and l for each parent so,

    L    l

L   LL  Ll

l    Ll    ll

In this case, one is pure dominant and two heterozygous whereas only one is recessive so, the phenotype of offspring that cant fol the tongue would be:

3/4 = 75%

55 Which of the following is an advantage of
Savatey [412]

<u>Answer</u>:

"It increases the mutation rate"  is an advantage of  sexual reproduction

<u>Explanation</u>:

The basic thing of evolution is fundamental, as it helps in generation of genetic variation on which the selection can act. Sexual reproduction leads to genetic diversity, and this genetic diversity leads to increase the mutation rate. Genetic diversity occurs because of two various cells which are combining together and biological assortment which happens at the time of cell division. Neutral genetic diversity in the population leads to high mutation rate.
