The correct answer is 'inbreeding depression'. This is when more recessive<span> traits are manifesting in the phenotype. Recessive traits can only occur in offspring if both parents contain the recessive gene, and this is much more likely under reduced genetic diversity due to inbreeding. </span>Many alleles confer a selective advantage in the heterozygous and/or homozygous-dominant state, whereas the homozygous-recessive state confers less or even no advantage.
Answer:
<h2>RrYy and rryy
</h2>
Explanation:
1. As given; Round seeds (R) are dominant on wrinkled seeds (r),
Yellow seeds (Y) are dominant on green seeds (g).
In a testcross, between an unknown genotype and a homozygous recessive with wrinkled and green seeds (rryy).
offspring are:
Round and yellow are 53; genotype (R_Y_)
round and green are 49; genotype (R_yy)
wrinkle and yellow are 44; genotype (rrY_)
wrinkled and green are 51 ; genotype (rryy)
Here, the genotype of parents of these offspring would be RrYy and rryy.

We are the cause of climate change. It is also caused by biotic factors such as variations in solar radiation received by Earth, plate tectonics, and volcanic eruptions.
